Because putnbr and putstr aren’t enough
One of the first projects is the recoding of the Printf function because 42 Students can't use a huge part of the built-in functions that C provides. The reimplementation will cover the following points:
- It must not do the buffer management like the real printf
- A format specifier follows this prototype: %[flags][width][.precision]specifier
- It will manage the following conversions:
| Specifier | Description |
|---|---|
| c | Character |
| s | String of characters |
| p | Pointer Address |
| d | Signed decimal integer |
| i | Signed decimal integer |
| u | Unsigned decimal integer |
| x | Unsigned hexadecimal integer |
| X | Unsigned hexadecimal integer (uppercase) |
| % | Two followed "%" will write a "%" |
- It will manage any combination of the following flags:
| Flags | Description |
|---|---|
| - | Left-justify within the given field width |
| 0 | Left-pads the number with zeroes (0) instead of spaces |
- It will manage minimum field width with all conversions
The library that contains the ft_printf function will be ready to use after the compilation process. To do so, just use make command at the root of the repository and it will create a libftprintf.afile.
Don't jump into the Libft folder! It is the first project that we made at 42 School and it contains a lot of functions that we need to recode to use it during other projects. To avoid confusion I will advise you to just see the functions that are used in this project that are listed below.
