The video tutorial introduces the concept of constants, explaining their role and significance in mathematical expressions and equations.

What is a constant in the context of programming?

• A variable that stores temporary data

• A fixed value that does not change

• A function that performs calculations

• A value that can change during program execution

Which of the following is an example of a constant?

• The value of pi (π)

• A user's age

• A random number

• The current temperature

How do constants differ from variables?

• Variables are always numbers, constants are not

• Constants can change, variables cannot

• Variables are fixed, constants are not

• Constants remain the same, variables can change

Why are constants important in calculations?

• They make programs run faster

• They ensure consistency and reliability

• They allow for dynamic changes

• They are easier to remember than variables

In which scenario would you use a constant?

• To store a user's input

• To hold a temporary value

• To calculate a changing interest rate

• To represent the speed of light
