ft_printf

This project is a re-writing of the standard C printf function, with all the same specifiers and flags. It is intended to be used to understand how variadic arguments work.

Specifiers

The following specifiers are supported by this project:

• c: Character
• s: String
• p: Pointer address
• d: Signed decimal integer
• i: Signed decimal integer
• u: Unsigned decimal integer
• x: Unsigned hexadecimal integer
• X: Unsigned hexadecimal integer (uppercase)
• %: A % followed by another % will write a single % to the stream

Flags

The following flags are supported:

• -: Left-justify within the given field width
• 0: Left-pads the number with zeroes (only when padding with zeroes is specified)
• .*: Precision
• #: Used with o, x or X specifiers the value is preceeded with 0, 0x or 0X respectively for values different than zero
• +: Forces to preceed the result with a plus or minus sign (+ or -) even for positive numbers. By default, only negative numbers are preceded with a - sign.

Usage

The printf function can be used in the following way:

int printf(const char *format, ...);

Where format is a string that contains one or more of the specifiers and flags mentioned above.

For more information on usage and examples, please consult the project documentation.

Enjoy!
