Why control flow directs program logic in MATLAB - Quick Recap

Recall & Review

beginner

What is control flow in programming?

Control flow is the order in which individual instructions, statements, or function calls are executed or evaluated in a program.

beginner

Why is control flow important in directing program logic?

Control flow decides which parts of the code run and when, allowing the program to make decisions, repeat actions, or skip steps based on conditions.

beginner

Name three common control flow structures in MATLAB.

The three common control flow structures in MATLAB are: <br>1. if-else statements<br>2. for loops<br>3. while loops

beginner

How does an if-else statement affect program logic?

An if-else statement lets the program choose between two or more paths based on a condition, so different code runs depending on the situation.

beginner

What happens if control flow is not used properly in a program?

Without proper control flow, a program might run code in the wrong order, repeat unwanted steps, or skip important actions, causing errors or wrong results.

What does control flow in a program determine?

A The order in which code runs

B The color of the text in the editor

C The size of variables

D The speed of the computer

Control flow determines the order in which the program's instructions are executed.

Which MATLAB statement is used to repeat actions a fixed number of times?

A if

B while

C for

D switch

The 'for' loop repeats actions a fixed number of times.

What happens when an if condition is false and there is an else block?

A The if block runs anyway

B The program stops

C The program crashes

D The else block runs

If the if condition is false, the else block runs to handle the alternative case.

Which control flow structure repeats code while a condition is true?

A for loop

B while loop

C if statement

D switch statement

A while loop repeats code as long as its condition remains true.

What is a risk of not using control flow correctly?

A Program may run code in wrong order

B Program will run faster

C Program will use less memory

D Program will have better graphics

Incorrect control flow can cause the program to run code in the wrong order, leading to errors.

Explain in your own words why control flow is essential for directing program logic.

Think about how a program decides what to do next.

Describe how an if-else statement changes the path of a program.

Consider what happens when the condition is true or false.
