how to find maximum number c++ code example

Example 1: c++ how to get maximum value

x = 1, y  = 2;
fmax(x , y);
//if you want to print it right away:
cout << fmax(x , y);
//if you want to store it:
int j = fmax(x, y);
cout << j;

//output 2

Example 2: maximum int c++

#include <limits>

int imin = std::numeric_limits<int>::min(); // minimum value
int imax = std::numeric_limits<int>::max(); // maximum value (2147483647)
