Jump to PostOne of your big big problems is code style -- it is absolutely horrible. Here is an example of a better coding style and is a lot easier to read.
int password(char usr_name[], char pwd[]) { int j=0,k=0,i=0,m=0,n=0; char corr[9],po[7]; corr[8] = "pizzaboy"; for(i=0;usr_name[i]!='\0';i++) { if (usr_name[i]== …
Jump to Post>>It demands header for end(), cout, endl;
See the header files in my post. All those are in <iostream>.As for the text placement, you still use setw() function.
int nSpaces = 23; int i = 0; // a loop counter cout << setw(0) << list[i] …

Itz 12:35 AM in In India..... and I also have to study for chemistry.Sorry, but my task is to just help you solve YOUR problem. What time it is in India is not my problem. I think with …
Jump to Postyou mean like this???
int main() { #include <string>That's not the way its done. put the headers at the top of the file so that they are global to everything in the file.
>>why int main() ??
every c++ program has a main function, its …
Jump to Post>>I mean why not void main() after all it dosen't return any int value it returns void value.
main() always returns a value whether you specify one or not. int main() and int main(int argc, char* argv[]) are the only two valid ways to declare it.
How about posting actual code so we know what advice to give you. :icon_rolleyes:
>corr[8]="pizzaboy"; error-- cannot convert char* to char
Presumably corr is declared as char corr[N]; , which means that corr[8] has type char, not char*.
>corr[]="pizzaboy"; error-- char has zero values
Presumably this isn't a declaration.
>corr[2]="z" ----- syntax error
Presumably corr is declared as char corr[N]; , which means that corr has type char, not char*. You specify a character literal with single quotes.
>corr[8]='pizzaboy' ------- char const can have 2 chars
You seem to be making every mistake humanly possible while actively avoiding the correct solution...
int password(char usr_name[], char pwd[])
{
int j=0,k=0,i=0,m=0,n=0;
char corr[9],po[7];
corr[8] = "pizzaboy";
for(i=0;usr_name[i]!='\0';i++)
{
if (usr_name[i]== corr[i])
n=1;
else
n=0;
}
po[] == "qwerty";
for(j=0;pwd[j]!='\0';j++)
{
if (pwd[j]== po[j])
m=1;
else
m=0;
}
if (m==1 && n==1)
k=1;
else
k=0;
return (k);
}btw what is char* ??
corr[8]="pizzaboy"; error-- cannot convert char* to char
That obvious. You're trying to put 9 chars in 1 char, so the compiler gives you an error
corr[]="pizzaboy"; error-- char has zero values
True. Replace it with char corr[]="pizzaboy";
corr[0]="p" corr[1]="i" corr[2]="z" ----- syntax error [/quote]If you asssign a single char to a char you need to use single quotes (and semicolons):
corr[0]='p';corr[8]='pizzaboy' ------- char const can have 2 charsThat's just silly :)
[edit] too slow, sorry about the double post Narue[/edit]
char corr[];
corr[]="passowrd";
error -- corr has unknown size or zero.
I am stuck with this error for 2-3 hrs now :'(
Did you actualy read anything I wrote?
Replace it with
char corr[]="pizzaboy";
YESSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS
My code is working now thanx :)
plz carify 1 more doubt sorry I have 2 submit my porj. tomoro.
how do I include the fn. ?
#include"FUNCTION.cpp" error-- cannot include file.
So DOES the file exist? In what file did you write the function? Show some code please.
#include<iostream.h>
#include<conio.h>
#include"FUNCTION.cpp"
void main()
{
clrscr();
char ur,pass; int y;
cout<<"Enter username and enter pasword"<<endl;
gets(ur);
cout<<"Enter password"<<endl;
gets(pass);
y=password(ur,pass);
if(y==1)
cout<<"Enter please"<<endl;
if(y==0)
cout<<"WRONG PASSWORD OR USERNAME"<<endl;
else
cout<<"Unknown error"<<endl;
getch();
}You didn't answer my question. IS the function you wrote in FUNCTION.cpp? If so: is FUNCTION.cpp in the same directory as main.cpp?
a few other points which will help your grade:
- it's int main() not void main()
- clrscr() might work fine with your old turbo C compiler, but it is not standard C
- gets() is a very dangerous thing to use
- use getchar() instead of getch()
no FUNCTION. is in my proj. folder.
and I am getting some weired errors such as
type mismatch in '__s' and and many other shit errors.
getch() in end is not for input itz for freezing the screen :)
Don't let my critisism demotivate you. A few more problems to solve and you're done :)
I'm signing off in about 10 min. But there are a lot of people here who are willing to help you, and most of them are more skilled then me ;)
[edit] you've changed your post...
>forget it I am having too much errors .....I quit of the proj.
If you can't handle the errors in that tiny program, I guess programming wasn't for you.
>sorry fr inconv. caused.
Not everyone is fluent enough in English to decipher this. Please use complete words and grammar as correct as you can manage.
[edit]
Replacing your entire post with something different is extremely rude.

sorry

Well put FUNCTION.cpp in you project folder, if that is the file where you put you function in.
I know what getch() is for. I still recommend you use getchar();
I put it in the main cpp folder and project and now still itz unable to open ?
I'm losing track with all your threads. Could you post ALL the code you have here and tell us which code is in which file and directory?
ok

One of your big big problems is code style -- it is absolutely horrible. Here is an example of a better coding style and is a lot easier to read.
int password(char usr_name[], char pwd[])
{
int j=0,k=0,i=0,m=0,n=0;

if (pwd[j]== po[j])
m=1;
else
m=0;
}
if (m==1 && n==1)
k=1;
else
k=0;
return (k);
}Notice that line 14 of the above code is an error. I don't know what you are attempting to do there.
>>#include"FUNCTION.cpp"
NEVER EVER do that. When there are two or more *.cpp or *.c files then they should be compiled separately and linked together with the linker.
>> gets(ur);
NEVER EVER for any reason use gets() function because it can crash your program by copying more characters from the keyboard buffer into the input buffer (ur in the above case) than the input buffer can hold. That is called buffer overrun and gets() will just scribble all over memory. To correct this, use fgets() instead, like this: fgets(ur, sizeof(ur), stdin); fgets() too has a small problem: it appends the '\n' (the Enter key) to the end of the string, so your program has to strip it off. That's one big reason not to use C functions in a c++ function because the C++ iostream class doesn't do that.
fgets(ur, sizeof(ur), stdin);
if( ur[strlen(ur)-1] == '\n')
ur[strlen(ur)-1] = 0;at 14 Im trying to enter the string to be stored in array po[].
>>they should be compiled separately and linked together with the linker.
both the fuctions are compiled seperatly !!
How do I link them with the main prog. is my porblem.
at 14 Im trying to enter the string to be stored in array po[].
Your age has nothing to do with the problem. use strcpy() to copy one string to another strcpy( po, "pizzaboy" ); , assuming po is a character array large enough to hold the string.
>>they should be compiled separately and linked together with the linker.

Depends on the compiler. Looks like you might be using Turbo C++, is that right? If it is, then just add each *.cpp file to the project separately and the IDE will link them correctly. That is just a matter of learning how to use your compiler.
BTW: please re-read my previous post because I added some more comments.
Yes I am using Tc++ v3.0 I suppose.
fgets is peety clumsy can I try using getche(); ?
[EDIT]Not my age 14 is the line number btw my age is 15. And strcpy is is good idea indeed ....btw po stores the correct pass and pwd is the one entered by the user. Also if I use strcpy instead of the loop won't the junk chars create prob. ??
