Cpp - Increment and Decrement Operators

This is a Cpp program to test increment and decrement operators. Increment operator increases the value by 1. Decrement operator decreases by 1. There are two types of increment and decrement operators ( pre and post) ++a  preincremeent (first increments the value for processing) a++ postincrement ( first time same value of a is used , then for after use it increments by 1) --a preincrement (first decrements the value for processing) a-- postincrement( first time same value of a is used , then for after use it decrements by 1)

PROGRAM :

#include <iostream>

using namespace std;

int main()
{
    int num1,num2,temp_num;
    cout << "Enter 1st number : \t" ;
    cin >> num1;
    cout << "\n Enter 2nd number : \t";
    cin >> num2;

    cout << "\nThe numbers before swapping : \t" << num1 << "\t"<< num2 << endl;

    temp_num=num1;
    num1=num2;
    num2=temp_num;

    cout << " \nThe numbers after swapping : \t" << num1 << "\t"<< num2 << endl;
    return 0;
}
