max value of int in c++ code example

Example 1: maximum int c++

#include <limits>

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

Example 2: how to set an integer equal to the largest integer possible in c++

// largest int in c++
signed int iMax = (unsigned int)~0 >> 1;
// largest unsigned int
unsigned int uMax = (unsigned int)~0;

Example 3: int max in c++

2147483647
  unsigned long long int = 18 446 744 073 709 551 615

Example 4: 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
