Code:

int main()

{ 

      

    char leftStr[] = "g f g";

    char rightStr[] = "g f g";

      

    // Using strcmp()

    int res = strcmp(leftStr, rightStr);

      

    if (res==0)

        printf("Strings are equal");

    else 

        printf("Strings are unequal");

      

    printf("\nValue returned by strcmp() is:  %d" , res);

    return 0;

}

Output: when both string are same it will return zero.

Strings are equal
Value returned by strcmp() is:  0
