Write a C++ program that uses functions to swap two integers.

#include(iostream.h) // place this '<' & '>' instead of '(' & ')' before iostream.h
#include(conio.h)
void swap(int, int);
void main( )
{
int x, y;
clrscr( );
cout<<"Enter the two numbers to swap:"; cin>>x >>y;
swap(x, y);
getch( );
}
void swap( int a, int b)
{
int temp;
cout<<"Values before swapping: "<< a <<"and"<< b;
temp=a;
a=b;
t=temp;
cout<<"Vaues after swapping:" << a <<"and"<< b;
}

Output: Enter the two numbers to swap: 10 20

Values before swapping: 10 and 20
Values after swapping: 20 and 10
