maximum value of int

Question

is there any code to find the maximum value of integer (which is acccording to the compiler) in c/c++ like Integer.MaxValue function in java

Answer 1

In C++:

#include <limits>

then use

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

std::numeric_limits is a template type which can be instantiated with other types:

float fmin = std::numeric_limits<float>::min(); // minimum positive value
float fmax = std::numeric_limits<float>::max();

---

In C:

#include <limit.h>

then use

int imin = INT_MIN; // minimum value
int imax = INT_MAX;

or

#include <float.h>

float fmin = FLT_MIN;  // minimum positive value
double dmin = DBL_MIN; // minimum positive value

float fmax = FLT_MAX;
double dmax = DBL_MAX;

Answer 2

#include <climits>
#include <iostream>
using namespace std;

int main() {
  cout << INT_MAX << endl;
}
