Function body will not differ in function Template, function body can differ in function overloading

The function template has only one definition for various types.
But its not the case for the function over loading.

For eg.,

#include "stdafx.h"
#include "stdio.h"
#include "windows.h"
#include<iostream.h>
#include "test.h"

template < class T>
T add(T a, T b)
{
 T c;

 c= a+b;
 
 return c;
}

int main()
{

 cout << add<int>(1,2)<<endl;
 cout << add<float>(1.0,2.0)endl;

return 0;

}


But for the function overloading there has to be different datatypes defined for each functions.

Function overloading is declaring function with same names but different return, parameter and datatype. It is like normal function with same name


Function template is a generic type of function in which we provide a structure for function and its upto which how we used it for which type of data
