Develop a computer program to solve a problem using a sequence of instructions : If Statements

This video tutorial covers the basics of if statements in JavaScript, including the use of else and else if clauses to handle multiple conditions. It provides practical examples, such as account management and user role scenarios, to demonstrate how these conditional statements work. The tutorial concludes with a challenge to create a temperature warning app, reinforcing the concepts learned.

What is the primary purpose of an if statement in programming?

• To repeat a block of code multiple times

• To execute a block of code based on a condition

• To define a new function

• To declare a variable

What does the else clause allow you to do in an if statement?

• Terminate the program

• Repeat the if condition

• Execute code when the if condition is true

• Execute code when the if condition is false

How does the else if clause enhance the functionality of if statements?

• It allows for multiple conditions to be checked in sequence

• It repeats the same condition multiple times

• It terminates the program if the condition is false

• It only works with numeric conditions

In the user role example, what message is displayed if the account is locked?

• Access Denied

• Welcome Admin

• Account is locked

• Welcome

What is the purpose of the else if clause in the user role example?

• To check if the user is an admin

• To check if the account is locked

• To print a generic welcome message

• To terminate the program

What is the expected output when the temperature is set to 45 in the temperature warning app?

• Go for it, it's pretty nice out

• Stay indoors

• It's hot outside

• It's freezing outside

Which condition would trigger the message 'It's freezing outside' in the temperature app?

• Temperature is greater than 110

• Temperature is less than or equal to 32

• Temperature is exactly 45

• Temperature is between 32 and 110

What happens if none of the if or else if conditions are met in a statement?

• The program crashes

• The else block is executed

• The first condition is executed by default

• The program skips the entire if statement

In the temperature app, what message is displayed if the temperature is 120?

• Stay indoors

• It's hot outside

• It's freezing outside

• Go for it, it's pretty nice out

What is the role of the else clause in the temperature warning app?

• To terminate the program

• To repeat the temperature check

• To provide a default message when no other conditions are met

• To handle cases where the temperature is exactly 32
