The goal of the ft_printf project is to recode the printf() function from the standard C library. This project introduces variadic arguments.
The ft_printf function Writes to the standard output according to the format string given as the first argument.
The format string contains normal characters and conversions introduced by the % character. The conversions will take the next argument of the function and write it to the standard output according to the type of conversion.
Supported conversions.
The bonus part manages additional flags for certain conversions. Supported flags.
Clone the project and run 'make' in the repository. For the additional functionality with flags run make bonus. This creates a library called 'libftprintf.a'. To use the function compile the library with your program and include the header files in the repository.
- d : The argument is an int and printed as a signed decimal
- i : The argument is an int and printed as a signed decimal
- c : The argument is an int and printed as an unsigned char
- s : The argument is expected to be a pointer to a string. The string is then written up to the NUL character
- p : The argument is a pointer and is printed in hexadecimal
- u : The argument is an unsigned int and printed as an unsigned int
- x : The argument is an int and printed in hexadecimal
- X : The argument is an int and printed in hexadecimal with capital letters
- % : the % sign is printed
- '+' : A sign will always be placed before a number, overrides space
- ' ' : A blank will be left before a positive number
- '0' : The converted value is padded on the left with zeros instead of blanks
- '-' : The converted value is padded on the right with blanks, instead of on the left with zero or blanks
- '#' : For x and X conversion the number will have the string "0x" or "0X" prepended to it
- precision : Gives the minimum number of digits for the number conversions or the maximum number of characters for the 's' conversion
- width : If the converted value has fewer characters than the width field, it will be padded with spaces on the left
