CPP - Variables

From Global Programming Syntax

Most of the time when making a program, numbers and integers will be needed to make calculations. Below is a simple script to show how to add to a number that has been typed in by the user:

#include <iostream>
using namespace std;
 
int main()
{
   int number; //defines the variable
 
   cout << "Please enter a number: "; // output the text
   cin >> number; //input a number
   number+=32; //this adds 32 to the number
   cout << "\nYour number+32 = " << number << "\n" << endl; //output the text
   system("PAUSE");
 
   return 0;
}

As you can see with the above example, the first indented line with int defines the number then the input/output begins. Also as shown in this script, the number integer has 32 added to it. In the way of integers, the above script is a very basic one...
