what's wrong with this password program

[brianvolkmann]

#include<stdlib.h>
#include<stdio.h>
#include<conio.h>
#include<string.h>
#define ff fflush(stdin);

void main()
{
int r;
char str1[10], str2[10];
clrscr();

 printf("Enter password:\n");
 gets(str1);
  ff;
  printf("Re-enter password:\n");
   gets (str2);
    ff;

     r=strcmp(str1, str2);

         if(r==0)
             {
                printf("Enter");
               }
                else
                  {
                      printf("Exit");
                    }
getch();
}

I only got 2 errors with the upper program:

1) the main () cannot be void with my compiler so i put in int main()

2) The function Clrscr(); is invalid. If you wanted to use the clear screen function then you can type cls; instead of it.

Thats it and then the program works fine.

===========================
But it is not anything like a password program .

Try doing this .Program.

#include<stdlib.h>
#include<stdio.h>
#include<conio.h>
#include<string.h>


int main()
{
int r;
char str2[10];
char str1[]="Password" ; // Replace the Password with the word "Password" Make sure the quoteS stay.

printf("Enter password:\n");
gets (str2);

r=strcmp(str1, str2);

if(r==0)
{
printf("Enter");
}
else
{
printf("Exit");
}
getch();

Hey Use the C++ Functions like Cin and cout with the Std namespace that will be easier.

This is what i get when i run the program that you posted, i have no idea how to fix it!

Hey Try compiling it with any other compiler or try this

#include<stdlib.h>
#include<stdio.h>
#include<conio.h>
#include<string.h>
#define ff fflush(stdin);

void main()
{
int r;
char str1[10], ;
clrscr();

printf("Enter password:\n");
gets(str1);
ff;
char str2[10]="password"; // TYPE THE PASSWORD HERE.
ff;

r=strcmp(str1, str2);

if(r==0)
{
printf("Enter");
}
else
{
printf("Exit");
}
getch();
}

Hey Try compiling it with any other compiler or try this

#include<conio.h>
[..]
void main()
[...]
clrscr();
[...]
getch();

That won't work on any other compiler because it isn't standard C. It will probably only work on Turbo C, which is outdated.

At brianvolkmann :

You have a bracket-mismatch. You need one closing bracket after getch() (which you should replace with getchar() by the way) and you need to add a return 0; to the code, because main is an int function.

Now I'm getting this error when i try to build the program.(microsoft visual is the only compiler i have available)

You still have a mismatch in brackets. Count how many opening and closing brackets you have. These two numbers should be equal. To avoid these kinds of problems, google for code-indention.

[edit] Here's a nice link about it [/edit]
