Variables

Let’s talk variables. But before what, let’s have a look at why we need variables.

Why Do You Need Variables?

You’ve thrown a party in which the menu consists of your famous soup and noodles. As your guests relish the soup, you go to the kitchen to ready the noodles. You suddenly realize that you don’t have enough clean bowls to serve the noodles! You grab the dirty ones and clean them quickly. You use the bowls previously used to serve soup to serve the noodles too. Day saved!

What are Variables?

The bowls at the party were used for serving different things. In computer programming terms, they are what are known as variables.

A variable is something that can take or store different values as the program is executed.

Just as the same bowl is used to store different things, a variable is used to store different values such as numbers or words.
