Concept explainers

Control structures

Control structures are block of statements that analyze the value of variables and determine the flow of execution based on those values. When a program is running, the CPU executes the code line by line. After sometime, the program reaches the point where it has to make a decision on whether it has to go to another part of the code or repeat execution of certain part of the code. These results affect the flow of the program's code and these are called control structures.

Switch Statement

The switch statement is a key feature that is used by the programmers a lot in the world of programming and coding, as well as in information technology in general. The switch statement is a selection control mechanism that allows the variable value to change the order of the individual statements in the software execution via search.

Question

### Processing Returned Values in Code

In this section, you will choose how the value returned by a method, `getCableBill()`, is processed. There are three options provided, each demonstrating a different way to handle the returned value.

#### a. Assigning the Value to a Variable
```java
myCableBill = getCableBill();
```
- Here, `getCableBill()` is called, and its returned value is assigned to a variable named `myCableBill`.

#### b. Formatting and Printing the Value
```java
System.out.printf("%nCable Bill: $%,.2f", getCableBill());
```
- This line uses `System.out.printf()` to format and print the cable bill amount. The `%n` is used for a new line, and `%,.2f` formats the number as a floating-point with two decimal places and commas as thousand separators.

#### c. Conditional Processing Based on Value
```java
if(getCableBill() >= 300.00)
```
- This conditional statement checks if the value returned by `getCableBill()` is greater than or equal to 300.00. Further actions will depend on the condition being met or not.

Each method serves a specific purpose, whether it's storing, displaying, or making decisions based on the data retrieved. Understanding how to effectively utilize these techniques is crucial in programming for managing returned values.

**Interactive Exercise: Understanding Return Values in Programming**

In this exercise, you'll explore how return values from functions are used in different contexts. Consider the function `getCableBill()` which returns a value. You have three scenarios to choose how the returned value is processed.

**Choose how the value being returned is processed:**

a. `myCableBill = getCableBill();`
- Options:
- *as an argument*
- *as an operand in a comparison*
- *as a value for a variable* (correct choice)
- *as a recursion*

b. `System.out.printf(%nCable: %d, getCableBill());`
- Options (selection not visible in the image):
- *as an argument* (correct choice)
- *as an operand in a comparison*
- *as a value for a variable*
- *as a recursion*

c. `if(getCableBill() >= 300.00)`
- Options (selection not visible in the image):
- *as an argument*
- *as an operand in a comparison* (correct choice)
- *as a value for a variable*
- *as a recursion*

Each scenario provides different options to identify the role of the return value in the code. Consider how the return value is utilized: as a variable assignment, a function argument, or part of a conditional comparison.
