C# example

Question

You are an elementary school teacher and explaining multiplication to students.
You are going to use multiplication by 3 as your example.
The program you are given takes N number as input. Write a program to output all numbers from 1 to N, replacing all numbers that are multiples of 3 by "*".

Sample Input
7

Sample Output
12*45*7

Answer 1

Well, you know how to take input, right? 😇 Console.ReadLine(). You need to convert that to a number because input comes as string data type (lesson about "taking input"): Convert.ToInt32(...)

Then you can take a loop, a for-loop for example, and inside you use an if-statement to find the numbers that are divisible by 3 (num%3 == 0).

With that you should be able to complete the task 🍀💕😇
