FUNCTION TEMPLATE

AIM:
         To implement a C++ program to swap the numbers using the concept of function template.

ALGORITHM:

Step 1:  Include the header files

Step 2:  Declare the template class.

Step 3:  Declare and define the functions to swap the values.

Step 4:  Declare and define the functions to get the values.

Step 5:  Read the values and call the corresponding functions.

Step 6:   Display the results.

PROGRAM:                 

#include<iostream.h>

#include<conio.h>

template<class t>

 void swap(t &x,t &y)

{

   t temp=x;

   x=y;

   y=temp;

}

void fun(int a,int b,float c,float d)

{

   cout<<"\na and b before swaping :"<<a<<"\t"<<b;

   swap(a,b);

   cout<<"\na and b after swaping  :"<<a<<"\t"<<b;

   cout<<"\n\nc and d before swaping :"<<c<<"\t"<<d;

   swap(c,d);

   cout<<"\nc and d after swaping  :"<<c<<"\t"<<d;

}

void main()

{

    int a,b;

    float c,d;

    clrscr();

    cout<<"Enter A,B values(integer):";

    cin>>a>>b;

    cout<<"Enter C,D values(float):";

cin>>c>>d;

    fun(a,b,c,d);

    getch();

}

SAMPLE OUTPUT:

Enter A, B values (integer): 10 20

Enter C, D values (float):    2.50 10.80

A and B before swapping: 10 20

A and B after    swapping:  20 10

C and D before swapping: 2.50 10.80

C and D after    swapping: 10.80 2.50

RESULT:

                Thus a C++ program to swap the numbers using the concept of function template is implemented successfully.
