To know the range of various types of data such as int, float, double, long, and so on can be represented by the header file <limits> The scopes of these types are defined in class Numeric_limits.

Class templates: Template <class t> numeric_limits

where T is the type of data we want to query, such as int, float, double, etc.

The function min (), max () can output the minimum and maximum values for that type.

Such as:

#include <iostream>
#include <limits>
using namespace Std;

int main () {
cout << numeric_limits<int>::min () << Endl;
cout << Numeric_limits<int>::max () << Endl;
return 0;
}
