compare char of string c++ code example

Example 1: c++ compare char

// 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
*/

Example 2: how to compare two char* in c++

#include <string.h>
...
if (strcmp(firstSTR, secondSTR) == 0) {
    // strings are equal
    ...
} else {
    // strings are NOT equal
}
