Q & A

What is the main topic of the video?

The main topic of the video is about conditional statements in C++, specifically focusing on 'if', 'else', and 'else-if' statements.

What example does the presenter use to explain conditional statements?

The presenter uses a shopping scenario where discounts are applied based on the total amount spent to explain conditional statements.

What are the two integer variables declared in the program?

The two integer variables declared in the program are 'biaya' (cost) and 'total' (the final amount after discount).

What condition is checked in the first 'if' statement?

The first 'if' statement checks whether 'biaya' is greater than 10.

What happens if 'biaya' is greater than 10?

If 'biaya' is greater than 10, a discount of 2 is applied to the total cost.

What output is displayed when the input is 2?

When the input is 2, the output displays that no discount is applied, and the total remains 2.

How does the program determine if a number is odd or even?

The program uses the modulus operator to check if a number is divisible by 2. If the remainder is 1, the number is odd; otherwise, it is even.

What is the output if the input number is 24?

If the input number is 24, the output states that it is an even number.

What does the presenter say about future topics related to conditional statements?

The presenter mentions that they will explore more advanced topics related to conditional statements in future videos.

What motivational message does the presenter conclude with?

The presenter concludes with a motivational message encouraging viewers to keep learning and stay enthusiastic about programming.
