Chapter 4: Problem 4

For an \(1 f\) statement to conditionally execute a group of statements, the statements must be enclosed in a set of _____

Short Answer

Expert verified
Answer: Curly braces `{}` are used to enclose a group of statements for a conditional execution using an "if" statement.

Step by step solution

01

Understanding the "if" statement

The "if" statement is used in programming to control the flow of the code. It evaluates a condition, and if that condition is true, it executes the following statements. If the condition is false, the code inside the "if" block will be skipped, and the execution will continue after the block.
02

Identify the correct structure for enclosing the statements

To group multiple statements in an "if" block, and have them conditionally execute, they must be enclosed using a set of curly braces `{}`. The statements inside the curly braces will be executed only if the condition is true.
03

Example of using an "if" statement with multiple statements inside

Here's an example, assuming that we are using a programming language where curly braces are used to define code blocks: ```c int grade = 85; if (grade > 60) { // Statements enclosed in curly braces will be executed only if the condition is true printf("Congratulations, you passed!\n"); printf("Your grade is %d.", grade); } ``` In this example, if the value of `grade` is greater than 60, both `printf` statements inside the curly braces `{}` will be executed. If the value of `grade` is less than or equal to 60, these statements will be skipped.
