#include<iostream>
using namespace std;
template<typename T>
void swapNo(T &a,T &b)
{
T temp;
temp=a;
a=b;
b=temp;
}
int main()
{
int
a,b;
cout<<"Enter
two numbers\t";
cin>>a>>b;

cout<<"The
swapped values are\t"<<a<<" "<<b;

Template is basically a generic class
which can be used for any datatype.
In C++ template is defined by the
following syntax.
template<class template_ name> or
template<typename template_name>
function template is the using template
for particular function. For example the bellow short program demonstrates the
use of function template in c++.
#include<iostream>
using namespace std;
template<typename T>
T add(T a,T b)
{
return
a+b;
}
int main()
{
int
a,b;
cout<<"Enter
two numbers\t";
cin>>a>>b;
cout<<"The
sum of two numbers is \t"<<add(a,b);
return
0;
}
Here the above function template adds two numbers of
integer type , we can give any type of datatype inside function as parameter
but both parameter should be of same type.

class intro
{
public:
intro()
{
cout<<"My
profession is : Student";
cout<<"\nMy
age is 20.";
cout<<"\nI

}
~intro()
{
cout<<"\nMy
profession is : Footballer";
cout<<"\nMy
age is 19.";
}
};
int main()
{
intro
obj;
return
0;
