TUTORIAL CODING CARA MENGGUNAKAN STATEMENT IF DALAM FLOWGORITHM - PART 2

Summary

In this tutorial, the host explains how to use an 'if' statement to determine if a given year is a leap year. The script walks through the four key conditions for leap years, including divisibility by 400, 100, and 4. The program is demonstrated using Flowgorithm, where the user inputs a year and the system outputs whether it's a leap year or not. Examples with the years 2021 and 2020 show how the conditions are applied. The video ends with a prompt to download the source code and encourages viewers to try the program themselves.

Takeaways

• 😀 The tutorial focuses on using the 'if' statement in Flowgorithm to determine whether a year is a leap year.
• 😀 Four key conditions determine whether a year is a leap year: divisibility by 400, 100, and 4.
• 😀 If a year is divisible by 400, it is guaranteed to be a leap year.
• 😀 If a year is divisible by 100 but not 400, it is **not** a leap year.
• 😀 A year divisible by 4 but not 100 is a leap year.
• 😀 If a year is not divisible by 4, 100, or 400, it is **not** a leap year.
• 😀 The modulus operator (`%`) is used to check divisibility (e.g., year % 4 == 0).
• 😀 The program starts by declaring an integer variable to store the year input.
• 😀 The program uses conditional statements to evaluate the leap year conditions sequentially.
• 😀 The tutorial demonstrates the process using examples like the year 2021 (not a leap year) and 2020 (a leap year).

Q & A

What is the main topic discussed in the video?

The main topic of the video is how to create a program that checks whether a year is a leap year or not using the 'if' statement in Flowgorithm.

What are the four conditions for a year to be a leap year?

1. If the year is divisible by 400, it is a leap year. 2. If the year is divisible by 100 but not by 400, it is not a leap year. 3. If the year is divisible by 4 but not by 100, it is a leap year. 4. If the year is not divisible by 400, 100, or 4, it is not a leap year.

What is the modulus operator in programming, and how is it used in this context?

The modulus operator (denoted as '%') returns the remainder of a division. In this context, it is used to check if a year is divisible by 4, 100, or 400 by checking if the result of the division has a remainder of 0.

How does the program check if a year is a leap year using the 'if' statement?

The program uses a series of 'if' statements to check the four conditions. If the year satisfies the first condition (divisible by 400), it is a leap year. If not, it checks the second condition (divisible by 100 but not 400), and so on.

What happens if none of the conditions for a leap year are met?

If none of the conditions are met, the program outputs 'Not a leap year'.

Why is checking if a year is divisible by 4 considered the easiest condition?

It is considered the easiest because it’s the first condition to check. If a year is divisible by 4, it's immediately identified as a leap year, skipping the need to check the other more complex conditions.

How does the program handle input and output in Flowgorithm?

The program first prompts the user to input a year. Then, it checks the year against the conditions using the 'if' statement. Finally, it outputs whether the year is a leap year or not based on the conditions.

What is the significance of the input prompt 'Enter year number' in the program?

The input prompt 'Enter year number' is used to inform the user that they need to input a specific year to check whether it is a leap year or not.

What happens if the input year is 2021 in the program?

If the input year is 2021, the program will output 'Not a leap year' because 2021 is not divisible by 4, 100, or 400.

Can the program be used to check years beyond 2021?

Yes, the program can check any year by inputting the desired year. It applies the same conditions to any input year to determine if it's a leap year or not.
