Write a function in C++ that exchanges data (passing by reference) using a swap function to interchange the given two numbers.
#include<iostream.h>
#include<conio.h>
void swap(float& x, float& y)
{
float t = x;
x = y;
y = t;
}
void main()
{
void swap(float&, float&);
float a, b;
cin >> a >> b;
cout << "a=" << a << "b=" << b << endl;
swap(a, b);
cout << "a=" << a << "b=" << b << endl;
getch();
}
