To swap the numbers using the concept of function template.
Algorithm
Step 1: Start the program.
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.
Step 7: Stop the program.
Program
/* Program to swap the number in C++ using the concept of function template
Pardeep Patel @ studywarehouse.com */
#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();
}
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
