Check out example codes for "string compare in c". It will help you in understanding the concepts better.

Code Example 1

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

int main()
{
    char str1[] = "abcd", str2[] = "abCd", str3[] = "abcd";
    int result;

    // 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;
}

Code Example 2

strcmp(leftStr, rightStr);
//compares ascii value and gives positive, negative or zero.

Code Example 3

strcmp(str1, str2) = 32
strcmp(str1, str3) = 0

Code Example 4

strcmp(char, char);

Code Example 5

// use: strcmp(string1, string2);

string a = "words";
string b = "words";

if (strcmp(a, b) == 0)
{
	printf("a and b match");
  	// strcmp returns 0 if both strings match
}

else
{
	printf("a and b don't match");
  	// strcmp returns anything else if the strings dont match
}
