Question

what is Simple variable ?

Expert Solution

Step 1

A simple variable is just basically a variable with only one single value.

Let us declare a variable named 'num' as integer type with value 10.

int num =10;

It is specific that the num variable contains one and only value 10, so it is a simple variable.

We can understand it better while comparing it with a non-simple variable, for example, a variable which is used within the conditional statement of a loop.
