Solution for Exercise 13-7

ex1307

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

int main()
{
    char password[]="taco";
    char input[15];
    int match;

    printf("Password: ");
    scanf("%s",input);

    match=strcmp(input,password);
    if(match==0)
        puts("Password accepted");
    else
        puts("Invalid password. Alert the authorities.");

    return(0);
}

Notes

* Perhaps the most important thing to remember when comparing strings in C is that the strcmp() series of functions do not return TRUE/FALSE values. They return zero when the strings compare, as shown at Line 14.
