A Template function to return minimum of 2 values.

Here is a very minimal example of a templete.

You should make sure that you understand this, before going on to more examples.

// Programmer: Janet Joy
// Example of template 
#include <iostream>
#include<string>
using namespace std;
template <typename T>
T minimum( T val1,  T val2)
{ 
	// Because it is template, it can accept any type that has < .
	T result = val1;
	if (val2 < val1) result = val2;
	return result;
}
int main() {
	int num=5;
	// Test with int
	cout << minimum(num, 3)<<endl;
	// Test with double
	double d1 = 3.5, d2 = 7.1;
	cout << minimum(d1, d2) << endl;
	// Test with character
	char c1 = 'a', c2 = 'b';
	cout << minimum(c1, c2) << endl;
	string s1 = "hello", s2 = "goodbye";
	cout << minimum(s1, s2) << endl;
    system("pause");
    return 0;
}
