Understanding Conditional Statements in Programming

The video tutorial explores decision-making in both daily life and computer programming. It introduces Boolean expressions to determine true or false conditions and explains how conditional statements, like if and if-else, guide program decisions based on these conditions. The tutorial uses a practical example of determining age eligibility for a PG-13 movie to illustrate these concepts.

Why is it important for programs to adapt to changing conditions?

• To ensure they always produce the same output

• To respond appropriately to different inputs and situations

• To make them run faster

• To reduce the amount of code needed

What is the primary purpose of a Boolean expression in programming?

• To create graphical user interfaces

• To determine the truthfulness of a condition

• To store large amounts of data

• To perform arithmetic operations

What is the result of a Boolean expression?

• A number

• A string

• A true or false value

• A list

What does an 'if' statement do in a program?

• It stops the program from running

• It stores data in a database

• It repeats a block of code multiple times

• It executes a block of code if a specified condition is true

Which statement is used to execute a block of code only if a specified condition is true?

• For loop

• While loop

• If statement

• Switch statement

In the example provided, what condition is checked to determine if someone can watch a PG-13 movie?

• If age is greater than 18

• If age is greater than or equal to 13

• If age is equal to 13

• If age is less than 13

What happens when the condition in an 'if' statement is false?

• The program crashes

• The 'else' block of code is executed, if present

• The 'if' block of code is executed

• The program does nothing

How can you add an 'else' statement to an 'if' statement?

• By using a loop

• By dragging out the 'if else' block or clicking the plus symbol

• By writing a separate function

• By using a switch statement

What is the role of an 'else' statement in a conditional structure?

• To terminate the program

• To execute code when the 'if' condition is true

• To provide an alternative action when the 'if' condition is false

• To repeat the 'if' condition

Which of the following is NOT a reason to use conditional statements in programming?

• To handle different scenarios in a program

• To execute code only when certain conditions are met

• To make decisions based on conditions

• To ensure the program runs the same way every time
