Function Templates:-Templates are used to achieve the generic programming. By using function template the code will be independent to any data type.

A template is used to create generic class or a function. By using function templates we have used the same function for different data types. The below Code will show you how to make the function templates.

Template.cpp

#include<iostream.h>
#include<conio.h>
template<class T>

inline T add(T a,T b)
{
    return (a+b);
}

void main()
{
clrscr();

//Add Two Integer Numbers
int a=2,b=3;
cout<<"Integer:="<<add(a,b);

//Add Two Floating Numbers
float x=2.5f,y=3.2f;
cout<<"\n\nFloat:="<<add(x,y);

//Add Two Double Numbers
double m=4.5,n=3.9;
cout<<"\n\nDouble:="<<add(m,n);

getch();
}

In above code we have define a function add as a function template and different data types int,float and double using the same function for addition.
