Which of the following is the definition of a constant?
A
A container which is used to store values such as the number of attempts a person tries to log on to a network.
B
A language that is similar to a real programming language, but is easier for humans to understand although it doesn’t actually run on a computer. It can easily be converted to a regular programming language.
C
A value that cannot be altered by the program during normal execution:the value stays the same.
D
Messages to explain to others, and often to remind yourself, what the code is intended to do.
Explanation: 

Detailed explanation-1: -In computer programming, a constant is a value that should not be altered by the program during normal execution, i.e., the value is constant.

Detailed explanation-2: -You use the Const statement to declare a constant and set its value.

Detailed explanation-3: -A constant is a value or number that never changes in expression; it’s constantly the same. For example, in the figure given above 36 and 82 are constant because its face value is 36 and 82 respectively. Its value never changes.

Detailed explanation-4: -A constant is a value that cannot be altered by the program during normal execution, i.e., the value is constant. When associated with an identifier, a constant is said to be “named, ” although the terms “constant” and “named constant” are often used interchangeably.

Detailed explanation-5: -Constant is an entity that refers to a fixed value of data and which cannot be modified. During execution/computation of programming, the value of a constant cannot be altered, it remains constant.
