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.
STEP6: Display the results.
STEP 7: Stop the program.
PROGRAM:

01	#include<iostream.h>

02	#include<conio.h>

03

04	template<class t>

05

06	void swap(t &x,t &y)

07

{

08

t temp=x;

09

x=y;

10

y=temp;

11

}

12

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

14

{

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

16	swap(a,b);

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

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

19	swap(c,d);

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

21

}

22

23	void main()

24

{

25

int a,b;

26	float c,d;

27

clrscr();

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

29	cin>>a>>b;

30	cout<<"Enter C,D values(float):";

31	cin>>c>>d;

32	fun(a,b,c,d);

33

getch();

34

}

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
