here's a way you can do this:


int x=1;
cout<<"Squares of numbers between 1-10"<<endl<<endl;
while(x<=10)
{
cout<<"Square of "<<x<<" is "<<x*x<<endl;
x++;
}

since you do know that only 5 random numbers will be the input

try using arrays after declaring float num1,num2...num5

then have something like


float numbers[5];
float temp1;...

try removing fixed and showpoint


cout << "sin(" << angle << ") = "
<< setprecision(4) << sin(angle) << endl;
cout << angle;

assignments should be done like this:


difference = amount_purchased-amount_payed;

row - selectedX = 2;

first off,you're lacking an equal sign if you are trying to compare values

that part is having an error because you used the assignment(=) operator
assignments should be...

one more thing

if you were asked to validate the input yearly gross
have something like this:


do{
printf("Enter your yearly gross salary :");
scanf ("%d",&yearlygross);
}while...

that should be

netincome=(yearlygross-totaldeduction)/12;

this one works for me:

cout<<"Enter number of grade input: ";
cin>>numgrade;
for (int x=0;x<numgrade;x++)
{
cout<<"Enter a grade in letter format: ";
...

oh yeah,i was actually using gets()

i just typed that code here

here's my actual code


cout<<"Input date:";
gets(date);
if (strncmp(date,"xxx xx xxxx",11)!=0)

char one[10];
char two[10];
int n;

cin>>one>>two;

for (n=0;n<11;n++)
{
if (strncmp(one[n],"xxxx xxxx",10)!=0 && strncmp(two[n],"x,xx xxx.",10)!=0)
cout<<"Mismatch";

no that wasn't actually quick
took me almost 5 hours,mostly searching the net

it does not yet save/load from a file
but it's ok since it's only for school and alot has been applied in my prog...

nevermind,i finished the prog.

to mods :

requesting for closure of this thread,thanks.

how can i output a character underlined? or set to bold face?

searched the net but i can't find anything about it

thanks for giving me an idea on where to start.

lol

you said



anything doesn't mean everything.

though not really much,i still know something in c++

well,it's safe to say that i'm not that someone.

i'm planning on creating a program for reservations (ex. rooms)

by analyzing my problem,the things i don't know how to are:

validating the date and whether the room inquired is available or...

don't forget to put semicolons after statements
anyway,

for the additional $15 if balance is < $400


if (begbal<400)
total_bank_fees += 15;

equation for check fees:

are you referring to the length of the string?

strlen

tot_cost=pprice*quantity;
if (quantity >= 10 && quantity <= 19) {
discount = tot_cost * .2; /*percent to decimal conversion: 20%/100% = .2*/
discounted_cost = tot_cost - discount; }

ughh

took me 2 hours to fix it myself
but finally i got it working

anyway

thanks alot,DangerDev

i now have ideas on arrays

i have a problem not related with arrays but decided to ask in this same thread anyway
because i think this question is not worthy of a new thread.

sorry for this mess but i think pasting here my...

ahhh i got it!!!!

cout<<"Items bought:\n\n";
for (;n!=0;n--)
cout<<items[n]<<endl;

yeah there's a switch before that
i didn't notice i included the case '1'

anyway

for(;parts!='x';n++) {

cout<<"Parts\n\n0 - quadcore\n1 - dual core";
...

yes

case '1':
for(int n=0;parts!='x';n++) {
cout<<"Parts\n\n0 - quadcore\n1 - dual core";
parts = getch();

...

const int max_items=100;
string items[max_items];

parts_page:
cout<<"Parts\n\n0 - quadcore\n1 - dual core";
parts = getch();
...

yes,that's what i thought,that arrays would do the trick

but the problem is i can't understand clearly how to use arrays. mind showing me how?it would be greatly appreciated.

in my case...

the user can buy as much items as he wants

then items bought be displayed after he's done choosing

that's the part i'm having a problem because the number of items being purchased depends on...

char item_purchased1;
char item_purchased2;
char item_purchased3;
//and so on...

//then

parts = getch();
switch (parts) {
case '0':

maybe what i need with this program are not arrays

someone who know some other way on how i can produce the output i want?

this would be my first time with arrays so i still have no idea how to use it
i'm thinking on using it on this program

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

oh,was that BEFORE the getline?

well,go with what works.

although the fflush is not preferred gurus

try to do the right thing
see how HERE (http://www.daniweb.com/forums/thread90228.html)

Dev-C++ (http://www.bloodshed.net/devcpp.html) for me.

you might want to try MS visualC++ 2008 express (http://www.microsoft.com/express/vc/)

haven't tried it yet though.

what do you mean in this part?



the "please enter date" and "title" appears at the same time??

try using fflush(stdin); <<after the getline part.

pause() is a self defined function made by duoas

but i think a plain cin.ignore() works fine
or maybe it's just me on my compiler though

here at home i'm using dev c++ and i do get the same "problem"

i use system("pause") which i think is not preferred by others,but it's just me using it to see the output
then i just remove it...

i did read.

what i'm asking exactly is when i declared globally:

using std::cin;
using std::cout;



the one's i'm using in statements would be

i was about to ask this question too

so what's the proper way?

i always do declare globally this one
using namespace std;


should i just declare this one globally instead (if i'm using it)

just an off-topic thought though




shouldn't the century be 20?

since i do not have any knowledge yet about these pointers,i want to ask questions

i don't have my source code with me now because i did that at school
i did something like this:

char* color;...
