Question

Write a simple program that accepts two number A and B. Assign A to B in two scenarios 1) assign A to B by pre-incrementing A and observe the output 2)assign A to B by post-incrementing A and observe the output 3) swap both values

Answer 1

Answer:

// CPP program to demonstrate pre increment

// operator.

#include <iostream>

using namespace std;

int main()

{

int x = 10, a;

a = ++x;

cout << "Pre Increment Operation";

// Value of a will change

cout << "\na = " << a;

// Value of x change before execution of a=++x;

cout << "\nx = " << x;
