Password Program

Hi,

I am required to write a program in which a user will enter a password, and this password will be reversed and compared with the reverse of the actual password. In this case, the correct password is 'fred', but the program will compare 'derf' with 'derf', and the tell the user the password is correct.

Here is my current code:

Code:

/* Password Program */
/* By Luke Sowersby */

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

#define pass1 "derf"
#define string_size 25
#define string_end (string_size-1)

void string_swap(char[],char[]);

void main(void)
{

    char pass2[string_size], backwards[string_size];
    printf("Please enter password:\n");
    gets(pass2);

    string_swap(pass2, backwards);

    printf("Backwards: %s",backwards);

    if (backwards=="derf")
        printf("\nPass is correct");
    else
        printf("\nPass is incorrect");
}

void string_swap(char string[], char swap[])
{
int i;

for(i=0;i<(strlen(string));i++)
    {
    swap[(strlen(string)-1)-i]=string[i];
    }
    swap[strlen(string)]=string[strlen(string)];
}

At the moment, the program will reverse the word, but does not successfully carry out the 'if' condition execution.

Can anyone help me please?

Thanks.

to compare strings use strcmp (read function description to know what the return value means)

Thanks... I managed to get it working.
