Chapter 4: Problem 24

A variable with ___________ scope is only visible when the program is executing in the block containing the variable's definition.

Short Answer

Expert verified
Answer: Block scope.

Step by step solution

01

Understand variable scopes

In programming, a variable's scope determines its visibility and lifespan throughout the code. There are mainly three types of variable scopes: global scope, local scope, and block scope. We need to find the one that matches the description given in the exercise.
02

Identify the variable scope described in the exercise

The exercise describes a variable that is only visible when the program is executing within the block containing the variable's definition. This description matches the concept of a block scope. A block-scoped variable is only visible within the block where it is defined and is destroyed once the block's execution is completed.
03

Conclusion

A variable with block scope is the one that is only visible when the program is executing in the block containing the variable's definition.

True or False When an if statement is nested in the if part of another statement, the only time the inner if is executed is when the expression of the outer if is true.
