Hey,
I was using some code to write int's defined by user to a file but found when you use

myfile.open ("lover_names.txt");
    myfile << firstLover << " " << secondLover << " " << lovePercent << "%\n\n";
    myfile.close();

It replaces the other text in the text file, the answer will most likely be simple but i don't know it, Help ASAP?

ok, thank you, ive decided to do whitch ever strategy is most effecdent, so would it be hammers idea?

i like hammers idea but i think im going to go for maj's solution, how would i save the names to file? i know how to write like this is a line etc, would i just do that? oh and how would i pair the two names tomorrow?

I get you, but not how to do that,

Could you please post a little example and then i would work on it from that

Thank you!

Hey,
I was just mucking around and made a simple random number generator and made a "love percentage game" but, if you re-open the .exe and type the same names in it gives another completely different percentage, would i save the names to do a file or some kind?

#include <iostream>
#include <conio.h>
#include <time.h>

using namespace std;

int main()
{
    char firstLover[20];
    char secondLover[20];
    
    unsigned int lovePercent;
    
    cout << "Enter The First Lovers Name: ";
    cin  >> firstLover;
    
    cout << endl << "Enter The Second Lovers Name: ";
    cin  >> secondLover;
    
    srand ( time(NULL) );
    
    lovePercent = rand() % 100 + 1;
    
    cout << endl << "Your Love Percentage Is : " << lovePercent << "%!";
    
    getch();
}

Please reply with help, A.S.A.P :)

Thank you!

#include <iostream>
#include <conio.h>

using namespace std;

class Cat
{
      public:
      
      unsigned int age;
      unsigned int weight;
      
      void Meow();
      void Feed();
      void Sleep();
};

void Cat::Meow()
{
     cout << "Meow" << endl;
}

void Cat::Feed()
{
     
     const char *Feed[] = 
     { 
           "Meoww (Cat's Happy To Eat)\n", 
           "Psshhh (Cat Is Not Hungry!)\n",
           "Zzz (The Cat's Asleep, Leave It Alone)\n"
           }; 
           
           cout << Feed[ rand() % 3 ];
}

void Cat::Sleep()
{
     cout << "Meowww Zzz (Cat Has Fallen Asleep)" << endl;
     cout << "Psshhh (The Cat Is Not Tired)" << endl;
     cout << "Zzz (The Cat Is Already Asleep)" << endl;
}

int main()
{
    Cat BlackMagic;
    
    BlackMagic.Feed();
    BlackMagic.Sleep();
    
    getch();
}

I didn't get the outcomes i wanted, it gave me some answers from Sleep and i put *Feed[] with the random ones?

Hey guys,

I was just reading again about classes and their functions and i made some code, the thing i want to do is have a function, eg.

void Cat::Sleep()

and have it to have three cout's and choose one of them to say at random,

Heres my code.

#include <iostream>
#include <conio.h>

using namespace std;

class Cat
{
      public:
      
      unsigned int age;
      unsigned int weight;
      
      void Meow();
      void Feed();
      void Sleep();
};

void Cat::Meow()
{
     cout << "Meow" << endl;
}

void Cat::Feed()
{
     cout << "Meoww (Cat's Happy To Eat)" << endl;
     cout << "Psshhh (Cat Is Not Hungry!)" << endl;
     cout << "Zzz (The Cat's Asleep, Leave It Alone)" << endl;
}

void Cat::Sleep()
{
     cout << "Meowww Zzz (Cat Has Fallen Asleep)" << endl;
     cout << "Psshhh (The Cat Is Not Tired)" << endl;
     cout << "Zzz (The Cat Is Already Asleep)" << endl;
}

int main()
{
    Cat BlackMagic;
    
    BlackMagic.Feed();
    BlackMagic.Sleep();
    
    getch();
}

int main()
{
    cout << (int)'£' << "\n";
    return 0;
}

The output of the above on my computer is -93. You'll have to change the local setting if you want to print that character from -93 because it doesn't print that with the standard American local setting.

My output is also -93, could you please show me how to change etc, many thanks

>> fossil compiler.
I'm using dev-c++, just using that for getch();

So is there noway of getting £ into my program?

Hey guys, i was bored so made a money converter, nothing is wrong with errors etc in the code but when i run my program, the pound sign is not valid, it comes up as a u with a accent on top, please help.

#include <iostream>
#include <conio.h>

using namespace std;

int main()
{
    unsigned int convertMoney;
    char moneySymbol;
    
    cout << "Enter whether you would like convert from £ / $ : ";
    cin  >> moneySymbol;
    
    switch (moneySymbol)
    {
           case '$':
           cout << endl << "Enter ammount to convert :";
           cin  >> convertMoney;
           cout << "$" << convertMoney << " = £" << (convertMoney * 0.508233381);
           break;
           
           case '£':
           cout << endl << "Enter ammount to convert :";
           cin  >> convertMoney;
           cout << "£" << convertMoney << " = $" << (convertMoney * 1.9676);
           break;
    }
    getch();
}

EDIT : I googled it and found this website, http://www.fileformat.info/info/unicode/char/00a3/index.htm
I looked and it told me to enter "\u00A3" for the pound sign, i did that put it came up with another symbol PLEASE HELP

Oops sorry.

I recompiled my program and went 6 ^ 2, and the answer was still one..

HELP?

Just editing my calculator and looking at what functions math.h had and i came across pow,

My program compiles and things like that so no error but if I'm not mistaken the answer is wrong.

6 ^ 1 = 6X6? = 36 (IS THAT CORRECT??)

JUST IN MY PROGRAM IF I USE 6^1 IT GIVES ME 1

(SORRY FOR DOUBLE POSTING)

I have noticed i kept using "blackmagic.bat" and re-read the posts and i need a bin file, would i just create a file in notebook and save it as blackmagic.bin?

Thank you all for all your help.

So people are mentioning editing the binary function, can you please show me how this could be done :S

Sorry about saying spam, what i meant was ive already got that, but now the posts edited, thank you very much. In your opinion is it worth adding binary?

It is in one case..

No offense but thats spam..

I need to know the answer for binary not something i already have..

BUMP..

So..

myfile.open ("blackmagic.bat");

Is that not any good?

Cool :D.

Thank you.

I kind of said no code, but when opening the file would i just use

myfile.open ("blackmagic.bat");

Many thanks.

So, what would be the best solution?

Hey,

Say if i made a program where people could register a account, but if they closed the window, the program would close and not remember passwords yeah? Well if i used the open file etc could i save the password's to a file so it remembered them?

Many Thanks.

PS. DO NOT POST CODE, I AM JUST ASKING

>(Visual C++, I'm Guessing)

Nope, DEV_C++ :)

Hey,
I was just mucking around when using rand() and noticed every time it comes out as a output of 41?

#include <iostream>

using namespace std;

int main()
{
    unsigned int randomNumber;
    unsigned int guess;
    unsigned int guesses;
    
    randomNumber = rand(); 
    cout << randomNumber << endl;
    
    system("PAUSE > nul");
}

Should i use srand() or something?

Ok, sorry about that, is it because i didn't use typedef?

#include <iostream>

using namespace std;

double FindArea();

int main()
{
    double width, lenght, area;
    
    cout << "How Wide Is Your Yard? : ";
    cin  >> width;
    cout << endl << "How Long Is Your Yard? : ";
    cin  >> lenght;
    
    area = FindArea(width, lenght);
    
    cout << endl << endl << "Your Yard Is " << area << " Square Feet!";
}

double FindArea(double& l, double& w)
{        
         return l * w;
}

NOW I GET to many arguments to function `double FindArea()'

thats the whole example..

http://newdata.box.sk/bx/c/htm/ch05.htm

Click on the link : Listing 5.1.

I really like the book as well, its fine except from that example i think

Hi,

I've been reading "C++ In 21 Days", I read functions a while back and decided to write some, i wrote the code and it gave me a error, so i copied and pasted code from the book and still got a error, you must see from my point of view if I'm learning a language i don't want to be tought the wrong things, thats like learning French and saying "Hallo" is hello, though the real hello is "Bonjour".

Heres the code non the less..

#include <iostream>

using namespace std;

unsigned short FindArea();

int main()
{
    unsigned short width, lenght, area;
    
    cout << "How Wide Is Your Yard? : ";
    cin  >> width;
    cout << endl << "How Long Is Your Yard? : ";
    cin  >> lenght;
    
    area = FindArea(width, lenght);
    
    cout << endl << endl << "Your Yard Is " << area << " Square Feet!";
}

unsigned short FindArea()
{
         unsigned short l, w;
         
         return l * w;
}

"too many arguments to function `short unsigned int FindArea()'

this challenging code your homework by any chance?

I'll try to add that :).

BTW, Do you think the layout is ok or should be changed a little?

Nice to see it working.
So jw, but was it homework or just boredom :)?

Maybe because you have "30" in your code?

If you don't need it get rid of it, else put a ; on end of 30

Thanks for the help, and yes i did change my post/code, Ive got to go now but when i return i'll add the options :) Thanks for all your help. I quite like my little program :)

Thanks,

Ive changed code to case sqrt..

THANK YOU!

Now i'll move onto sin, cos and tan.

But would i do the same thing?

Like Y/N because what happens if they input two Y's for different things?

Because atm my program only takes 2 integers (or 1 for square rooting)

if ( boolSqrt != 'Y' || boolSqrt != 'y' && boolSqrt != 'N' ||
              boolSqrt != 'n')
         {
         cout << "\n WRONG DECISION.";
         }

Still doesn't work..?

EDIT!!!

Got sqrt working!! WOO :)

Could i not add a bool or something?

Sorry for misunderstanding. Thanks for the multiplication classes, would it be "hard" to add sin, cos and tan?

>Will they be an improvement? Probably not

I am going to improve it yes. I am going to make it have more options, square root, etc etc

Hey, i was just messing around and made a calculator and was just wondering if there was a way i could make it shorter? I'm not really bothered i just want to know?

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    system("TITLE My Calculator Program.");
    system("COLOR 4");
    
    double firstNumber, secondNumber;
    char operation; 
    
    cout << "NOTE: YOU CAN USE X/x INSTEAD OF * FOR MULTIPLICATION!\n\n\n\n";  
    
    cout << "Please enter the first number : ";
    cin  >> firstNumber;
    
    cout << "\nWhich type of calculation would you like to use? : "; 
    cin  >> operation;
    
    cout << "\nPlease enter the second number : ";
    cin  >> secondNumber;
    
         
         switch(operation)
         {
                          case '+':
                          cout << "\nAnswer = " << (firstNumber + secondNumber);
                          break;
                          
                          case '-':
                          cout << "\nAnswer = " << (firstNumber - secondNumber);
                          break;
                          
                          case '*':
                          cout << "\nAnswer = " << (firstNumber * secondNumber);
                          break;
                          
                          case 'x':
                          cout << "\nAnswer = " << (firstNumber * secondNumber);

                          cout << "\nAnswer = " << (firstNumber * secondNumber);
                          break;
                          
                          case '/':
                          cout << "\nAnswer = " << (firstNumber / secondNumber);
                          break;

Thanks.

I never said i cant use sqrt() i just said i dont know if it's worth it

I've looked at websites etc, but tbh is it worth it?

Thanks but i think i'll leave that option out

Hey i've made a simple calculator, but i was thinking about adding a square root option..

But is there a actual way to do this or would i have to create my own??

PLEASE REPLY A.S.A.P

Actually i'm trying to improve this now, i've figured i'll need a loop?

Because i want to change it so that if the user inputs a different char/int than Y/N it will cls and re-ask question,

Heres what i've got

/* Simple users decision to exit program */

#include <iostream>
#include <conio.h>

using namespace std;

int main()
{
    char exit;
    
    cout << "Exit? Y / N " << endl;
    cin >> exit;
    
    if ( exit == 'Y' || exit == 'y' )
       { }
       
    if ( exit == 'N' || exit == 'n' )
        getch();
        
    else
        system("cls");
        cout << "Exit? Y / N " << endl;
        cin >> exit;

}

If the user enters another char/int it cls's and asks again but if they enter a char/int again it closes, please help :)

Thanks! Just one thing, would i use a array to make the password a maximum of 20? Or ..?

Please show code. :)

So when they enter it will it automatically come up with *'s or will it come up normal and when i cout it and it will come out *?

Because ideally i would like no normal letters, just *'s :)
