Question
________ is the token which once initialized doesn’t change throughout the program.
Options:
- constant
- operator
- variable
- string
Solution
The correct answer is constant.
A constant in programming is a type of variable whose value cannot be changed once it has been initialized. This feature makes constants useful for values that are meant to remain the same throughout the execution of a program, such as mathematical constants (like π) or configuration values (like the number of maximum users).
In most programming languages, constants are defined using specific keyword declarations (such as const in JavaScript or C++) to indicate their read-only status. This helps prevent accidental changes to values that are crucial to the program's function and increases maintainability and readability.
In summary, when considering which type of token remains unchanged throughout a program, the term "constant" is the most appropriate choice.
