Where are Variables Stored?

In this lesson, you'll get the idea of how variables are stored in the memory.

We'll cover the following

Introduction

A variable is a place in memory where the application can store some type of information.

You can think of memory as an "array of bytes". Each byte possesses a memory address.

Upon variable declaration, a memory location is reserved for that variable.

Example

For example, we declare an int variable which covers 4 bytes and a char variable which spans over 2 bytes of memory:

Press + to interact
using System;
namespace VariablesExampleOne
{
    class Program
    {
        static void Main(string[] args)
        {
            int myInt;
            char myChar;
        }
    }
}

You’ll learn more about variables’ types ahead.

💡Note: 1 byte = 8 bits

Cool, right? Let’s learn the variable syntax in the next lesson. ​
