How to check if Two Strings are Equal in C ?

Answer

In C, you can use the strcmp function from the C standard library to check if two strings are equal.

✐ Examples

1 Check Equality using strcmp Function

In this example,

We include the string.h header file for the strcmp function.
We create two string arrays str1 and str2 with the same value "Hello".
We use the strcmp function to compare str1 and str2, which will return 0 if they are equal.
Finally, we check if the return value is 0 to determine if the strings are equal.

C Program

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

int main() {
    char str1[] = "Hello";
    char str2[] = "Hello";
    int result = strcmp(str1, str2);
    if (result == 0) {
        printf("Are strings equal? Yes");
    } else {
        printf("Are strings equal? No");
    }
    return 0;
}

Output

Are strings equal? Yes
