Question

I would like to mainly know the working of a for loop. For this I think a small sample program will be helpful to me. So what is a simple program to display the first N natural numbers?

Answer 1

If you are talking about Windows batch programming here you have a natural numbers generator:

for /L %i IN (0,1,9) do @echo %i
