number only in csharp

To print numbers in C#, you can use a for loop or a while loop. Here is an example of how to print numbers from 1 to 10 using a for loop in C#:

main.cs
for (int i = 1; i <= 10; i++)
{
    Console.WriteLine(i);
}
60 chars
5 lines

This code declares a variable i and initializes it to 1. It then performs an iteration while i is less than or equal to 10. In each iteration, it prints the value of i to the console using Console.WriteLine(), and then increments the value of i by 1 with i++.

You can use a similar loop to print numbers with different starting and ending values, or with a different increment. For example, to print even numbers from 2 to 20, you could use:

main.cs
for (int i = 2; i <= 20; i += 2)
{
    Console.WriteLine(i);
}

This example initializes i to 2, and then increments it by 2 in each iteration with i += 2.
