As we have understood till now, variables are basically like nouns in a programming language. Every variable in a program is unique. To identify these variables uniquely, user needs to allocate them a unique name. This name acts as an identifier for that variable. In programming, a user is not allowed to use the same name of a variable more than once.
Naming variables make it to easier to call them while performing operations. The name of a variable also suggests what information the variable contains.
You can refer to the example before for better understanding about variables:
If variable named as "a" is equal to 2 and variable named as "b" is equal to 2, performing add operation on "a" and "b" is going to result into an output as "4".
