This is a C language implementation of the printf function. It provides functionality for formatting and printing output to the console or file, using a format string and variable arguments. The implementation consists of the following 15 files:
README.md: This file you are currently reading.printf.c: The main implementation of theprintffunction.functions.c,functions1.c,functions2.c: Helper functions for handling different conversion specifiers, such as integers, strings, and characters.get_size.c,get_precision.c,get_flags.c,get_width.c: Functions for parsing and extracting information from the format string.handle_print.c: A function for handling the actual printing of formatted output.utils.c: Utility functions used by other parts of the implementation.write_handlers.c: Functions for writing different types of data to the console or file.main.h: Header file defining function prototypes and some global constants.
To use the printf function, include the main.h header file and call the printf function with a format string and any required arguments. For example:
#include "main.h"
int main() {
printf("Hello, %s!\n", "world");
return 0;
}This will output Hello, world! to the console.
To compile the printf function, simply include all of the source files in your build process. For example:
gcc -Wall -Werror -Wextra -pedantic -std=gnu89 *.c -o my_programThis will create an executable program called my_program that can be run from the command line.
