Why there is x = 9 and x < 19?

Number start from 1 so there should be x = 1

And you have to take input so your loop should be like :

while (x <= input) {

x++;
}

Print * when x % 3 == 0 otherwise print x

Answer 3

TheMasterBee

x should be initialise with 1 and semicolon missing

Answer 4

First you need to understand the question properly otherwise you could not able to solve this question
Suppose you enter 7
Now it will return 12*45*7
Here 'star' present in place of 3,6 as they are multiple of 3.
Here just using a for loop with a condition
for(int i=1;i<input+1;i++)
{
if(i%3==0)
{
Console.Write("*")
}
Console.Write(i)
}

Answer 5

You create a loop from 1 to N including. Then you use the remainder operator to check if the numbers are multiples of 3.

Answer 6

Can you write??

Answer 7

First, you should make an attempt by yourself, and then we can correct you if your code doesn't work as expected.

Answer 8

Ok fine

Answer 9

class Program
{
static void Main(string[] args)
{
int number = Convert.ToInt32(Console.ReadLine());
int x = 1;
while (x<=number)
{
if (x%3!=0)
Console.Write(x);
else
Console.Write("*");
x++;
}

}
}
