Answer 2

Answer:

The answer to the given question is:

b is variable, a is constant

Explanation:

A constant is a value that the programme cannot change while it is normally running, i.e., the value is constant. Although the phrases "constant" and "named constant" are frequently used interchangeably, a constant is considered to be "named" when it is coupled with an identifier. Unlike a variable, which is an identifier with a variable value that might vary during normal execution, a variable is not fixed.

A variable is a piece of data whose value may change while the programme is running. So, just as its name suggests, the value might change.

There are two uses for constants. As follows:

genuine constant

known constant

Anywhere a value is required, you write it into your programme as a literal constant.
