C++ Developer - Selection Control Statements

The video tutorial covers the three categories of control statements: sequential, selection, and repetition. It focuses on selection control statements in C, including if, if-else, and switch statements. The tutorial explains how these statements work, their syntax, and provides practical coding examples. It also includes a challenge to apply these concepts in a real-world scenario, emphasizing the importance of understanding and articulating programming constructs.

What are the three categories of control statements discussed in the video?

• Iteration, Decision, Execution

• Looping, Conditional, Branching

• Sequential, Looping, Conditional

• Sequential, Selection, Repetition

Which of the following is NOT a selection control statement in C?

• if statement

• for loop

• if-else statement

• switch statement

In the age-based program example, what is the legal drinking age used in the United States?

• 20

• 21

• 19

• 18

What does the if-else statement allow you to do that the if statement alone does not?

• Repeat a block of code multiple times

• Choose between two actions based on a condition

• Perform a single action based on a condition

• Execute multiple blocks of code simultaneously

How can you simulate multiway selection using if-else statements?

• By using a for loop

• By using a switch statement

• By chaining multiple if-else statements

• By using nested if statements

What is the main advantage of using a switch statement over if-else statements?

• It is more flexible

• It naturally provides multiway selection

• It is easier to read

• It uses less memory

In the switch statement example, what happens if a break statement is omitted?

• The switch statement will be ignored

• The default case will execute

• The next case will automatically execute

• The program will crash

What is the purpose of the default case in a switch statement?

• To execute only if a break is present

• To execute when all cases match

• To execute when no other case matches

• To execute before any case

In the challenge exercise, what condition must be met for a user to qualify for the discount?

• Age over 50 and gender 'M'

• Age 60 or over and gender 'F'

• Age 60 or over and gender 'M'

• Age over 50 and gender 'F'

What logical operators are suggested for use in the challenge exercise?

• Assignment operators

• Bitwise operators

• Relational and logical operators

• Arithmetic operators
