ninjapiraatti / ft_printf

Do printf in C practically without any libraries.

Hive Helsinki: ft_printf

Challenge

The versatility of the printf function in C represents a great exercise in programming for us. This project is of moderate difficulty. It will enable you to discover variadic functions in C in a particularly relevant context as well as learn about a great example of a basic “dispatcher” in C via the use of an array of function’s pointers.

Solution

Nothing spectacular, structs and loops.

In hindsight

I opted for writing a helper function that had to handle way too much. This caused problems both with the school's style guide and debugging as the code turned into spaghetti.
