disallow negative numbers..

is there an exception for negative numbers?

i'm trying to create a program which takes the user's input like this:

input a positive integer: 5

System prints out "good job" after

then repeats the question until the user types 0.

I got that part working but if i input something like this:

input a positive integer: -2

System prints out "Positive integer please!" and then takes the users input again until they input a positive integer or 0, then the program will output the other statements.

i'm thinking of creating a while loop but i don't know where to put it so that the program reverts back to "input a positive integer" after the person does so instead of "Positive integer please!"

Thanks in advnace!
