std max from m,ultiple caliue code example

Example 1: max three values c++

int a = 1;
    int b = 2;
    int c = 3;

    int m = std::max({a, b, c});

Example 2: max c++

// max example
#include <iostream>     // std::cout
#include <algorithm>    // std::max

int main () {
  std::cout << "max(1,2)==" << std::max(1,2) << '\n';
  std::cout << "max(2,1)==" << std::max(2,1) << '\n';
  std::cout << "max('a','z')==" << std::max('a','z') << '\n';
  std::cout << "max(3.14,2.73)==" << std::max(3.14,2.73) << '\n';
  return 0;
