Increment-Decrement a number in C++

Increment means to add or increase, decrement means to deduct or decrease. This c++ program will demonstrate how to increment and decrement a number. The user will be given an option to either increment or decrement a value, then the user will be ask to enter a number, the program will then perform the operation selected by the user.

If you’re using codeblocks, kindly open the incrementdecrement project file, you can also open the main.cpp in codeblocks.
Source code:

#include < iostream >

using namespace std;

int main()
{
    int selection, number;
    cout << "selection: " << endl;
    cout << "enter 1 to increment a number: " << endl;
    cout << "enter 2 to decrement a number: " << endl;
    cin >> selection;
    cout << "enter a number: " << endl;
    cin >> number;
    cout << "------------------" << endl;
    if (selection == 1)
    {
        number++;
        cout << "result: " << number << endl;
    }
    else
    {
        number--;
        cout << "result: " << number << endl;
    }
