External functs.

Notes of interest

My strategy for this was the following:

1. make a string up till to the conversion
2. make a string of the conversion with the flags ('-0.*' and minimum width) in regard
3. make a string of the rest
4. if more then one conversion go to step 1
5. join them

Since at Codam

• we have to protect our mallocs
• in case of a malloc fail, all other allocated memory needs to be freed
• the exit() function is not on the list of allowed/external functions
• it became a meme at Codam to fail peers during an evaluation if a malloc was maybe not that well protected

I figured it would be wisely to malloc as little as possible.

However during the project I realized if taken the easy approach for the conversions, I needed to malloc several times in case of flags being used. So my new approach was to calculate the exact amount of characters for the conversion so I only needed to malloc once for the conversion. Once this step was taken, I realized I could also write character for character without using malloc at all.

So for the sake of a challenge I got rid of all the mallocs and the result is the World's First Printf without use of Malloc (official title) and a much easier peer evaluation :).
