C - _printf

Description

First Holberton-School group project.

Clone of C function printf. Writes the C string pointed by format to the standard output (stdout).

If format includes format specifiers (subsequences beginning with %), the additional arguments following format are formatted and inserted in the resulting string replacing their respective specifiers.

Specifiers:

Type	Desc.
%c	prints a character
%s	prints a string
%p	prints '%'
%d	prints a decimal
%i	prints an integer

Requirements

• All your files will be compiled on Ubuntu 20.04 LTS using gcc, using the options -Wall -Werror -Wextra -pedantic -std=gnu89
• Code uses the Betty style.
• No global variables are allowed.
• No more than 5 functions per file.
• All prototypes of all functions are included in header file main.h.

---

Compilation & Testing

Function porototype:

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

We compile with:

gcc -Wall -Wextra -Werror -pedantic -std=gnu89 -Wno-format *.c

Example

Print a string:

   int x = 0;

   char *string = "Otaku";

   x = _printf("I'am am an%s, string);

   printf("%s, x);

   return (0);

Print an integer:

int x = 0;

int prints = 420;

x = _printf("It's:%i", prints);

printf("%i", x);

return(0);
