Question

Identify the false statement.

a. To execute more than one statement that depends on the evaluation of a Boolean expression, you use a pair of curly braces to place the dependent statements within a block.
b. When you declare a variable within a block, it is local to that block.
c. Indentation can be used to cause statements following an if statement to depend on the evaluation of the Boolean expression.

Answer 1

The false statement is 'c,' as indentation alone does not cause statements to depend on a Boolean expression's evaluation; control structures like if statements are required for conditional execution.

Step-by-step explanation:

The statement to identify as false is: 'c. Indentation can be used to cause statements following an if statement to depend on the evaluation of the Boolean expression.' This statement is false because indentation is a matter of style and readability in most programming languages, but it does not control the flow of execution. In languages like Python, indentation is syntactically significant, but it does not cause statements to execute differently based on a Boolean expression; the proper use of control structures such as if statements does that.

The correct statement should be: 'A proper control structure, such as an if statement, is required to execute statements conditionally based on the evaluation of a Boolean expression.' Both other statements, 'a' and 'b', create a block of code using curly braces and local variables scoped to a block are indeed true.
