How does a person make a character print more than once?

Question

I've watched all the videos for pset1 and I cannot figure out how to make the space or indention print out more than once. Can anybody tell me where I'm supposed to find that kind of information? or just how to do it?

Answer 1

Investigate loops. Here's the Loops Short: http://www.youtube.com/watch?v=HHmiHx7GGLE

Also, watch Week 2 Monday's lecture for more insights.

for (int i = 0; i < 5; i++)
{
    printf("Hi! ");
}

The output of this is:

Hi! Hi! Hi! Hi! Hi!

Answer 2

This may not be the best way, but a simple way to repeat the characters can be done like this (as this answer suggests)

Short answer - yes, long answer: not how you want it.

You can use the %* form of printf, which accepts a variable width. And, if you use '0' as your value to print, combined with the right-aligned text that's zero padded on the left..

printf("%0*d\n", 20, 0); 

produces:

00000000000000000000

It does have some limitations, and honestly, I have no ides how it works, but I did manage to execute mario with it.
