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

Code Example 1

// syntax
#include <cstring> // this needs to be at the top of the script/code
std::strcmp(<1st-char>,<2nd-char>)
  
// example (assuming: char_1 = 'Compare me'; char_2 = 'Compare_me')
#include <cstring>
if (std::strcmp(char_1,char_2) == 0) {
 std::cout << "The char's that you compared match!" << std::endl; 
}
else {
 std::cout << "The char's that you compared DON'T match" << std::endl; 
}

// OUTPUT: The char's that you compared match!

/*
NOTE: the following outputs of std::strcmp indicate:
[less than zero] : left-hand-side appears before right-hand-side in lexicographical order
[zero] : the chars are equal
[greater than zero] : left-hand-side appears after right-hand-side in lexicographical order
*/

Code Example 2

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


int main() 
{  
      
    char char1[] = "coucou"; 
    char char2[] = "coucou"; 
      
  	if( strcmp(char1, char2) == 0 )
       printf("Strings are the same");
  
  	else
      prinf("Strings are differentes");
  
  
    return 0; 
}
