Getting the Minimum and Maximum Values for a Numeric Type

Getting numeric limits

#include <iostream>

#include <limits>

using namespace std;

template<typename T>

void showMinMax() {

cout << "min: " << numeric_limits<T>::min() << endl;

cout << "max: " << numeric_limits<T>::max() << endl;

cout << endl;

}

int main() {

cout << "short:" << endl;

showMinMax<short>();

cout << "int:" << endl;

showMinMax<int>();

cout << "long:" << endl;

showMinMax<long>();

cout << "long long:" << endl;

showMinMax<long long>();

cout << "float:" << endl;

showMinMax<float>();

cout << "double:" << endl;

showMinMax<double>();

cout << "long double:" << endl;

showMinMax<long double>();

cout << "unsigned short:" << endl;

showMinMax<unsigned short>();

cout << "unsigned int:" << endl;

showMinMax<unsigned int>();

cout << "unsigned long:" << endl;

showMinMax<unsigned long>();

cout << "unsigned long long:" << endl;

showMinMax<unsigned long long>();

}
