(A) Answer the following questions.

1) What is constant?

Definition: A constant is a fixed value that cannot be changed during the execution of a program. Once a constant is assigned a value, the program cannot modify it. Constants bring safety and clarity — they protect important values (like mathematical constants, fixed limits, configuration settings) from accidental change.

Constants can belong to any data type:

• Integer constant: 10, -5, 0
• Character constant: 'A', '9', '$'
• Floating-point constant: 3.14, 2.5f
