Variable Scope | MCQs

Explanation

A variable is a named memory location whose value can change during the execution of a program.

In contrast, a constant has a fixed value that does not change while the program runs.

Explanation

Variable scope refers to the extent of code in which a variable can be referenced.

Variables defined inside a function are called local variables.

The scope of local variables and dummy arguments is limited to the function in which they are defined.
