c++ cp template code example

Example 1: c++ template

#include <iostream>
using namespace std;

template <typename T>
void Swap(T &n1, T &n2)
{
	T temp;
	temp = n1;
	n1 = n2;
	n2 = temp;
}

int main()
{
	int i1 = 1, i2 = 2;
	float f1 = 1.1, f2 = 2.2;
	char c1 = 'a', c2 = 'b';

	cout << "Before passing data to function template.\n";
	cout << "i1 = " << i1 << "\ni2 = " << i2;
	cout << "\nf1 = " << f1 << "\nf2 = " << f2;
	cout << "\nc1 = " << c1 << "\nc2 = " << c2;

	Swap(i1, i2);
	Swap(f1, f2);
	Swap(c1, c2);

        cout << "\n\nAfter passing data to function template.\n";
	cout << "i1 = " << i1 << "\ni2 = " << i2;
	cout << "\nf1 = " << f1 << "\nf2 = " << f2;
	cout << "\nc1 = " << c1 << "\nc2 = " << c2;

	return 0;
}

Example 2: template c++

template <class identifier> function_declaration;
template <typename identifier> function_declaration;

//Example:
template <class Type> 
void Swap( Type &x, Type &y)
{
    Type Temp = x;
    x = y; 
    y = Temp;
}

Example 3: template c++

template <class myType>
myType GetMax (myType a, myType b) {
 return (a>b?a:b);
}
