C Language Problem

Start with the HELLO WORLD example first and work yourselves up to the climax.

Sounds like a homework problem.

I don't want to do the assignment for you, but if you can show us what you have so far and then ask a specific question, there will be people willing to help round out your education by guiding you.

This isn't C language, but just do pretty much what you already said:

If (number) ≤ 0, then print "Invalid input. Please enter an integer greater than 0."

Or something like that, translated into C.

(Interesting problem, by the way, if it's the one I'm thinking of. Try 27.)

if (input>0)

{

do

{

set of instructions;

}

while(condition);

}

else

if (input<=0)

{

printf(" error message");

}

Hope that helps!!! the content of the error message to be at your discretion

NO!
