Answer:

A storage class represents the visibility and a location of a variable. It tells from what part of code we can access a variable. A storage class is used to describe the following things:

The variable scope.

The location where the variable will be stored.

The initialized value of a variable.

A lifetime of a variable.

Who can access a variable?
