how to compare strings in c

int main()

    // comparing strings str1 and str2
    result = strcmp(str1, str2);
    printf("strcmp(str1, str2) = %d\n", result);

    // comparing strings str1 and str3
    result = strcmp(str1, str3);
    printf("strcmp(str1, str3) = %d\n", result);

    return 0;
}

                                    char str1[] = "Look Here";
char str2[] = "Look Here";

int i = strcmp(str1, str2);

                                    strcmp(char, char);
