ft_printf

Description

ft_printf is a custom implementation of the standard printf function from the C programming language. It is designed to mimic the behavior and functionality of printf, enabling formatted output to the standard output. This project focuses on understanding variadic functions, handling different format specifiers, and creating flexible output functions in C.

Objective

The main objective of this project is to:

• Reimplement the printf function from the C standard library.

• Format specifiers: The implementation supports common format specifiers, including:

  • %c Prints a single character.
  • %s Prints a string (as defined by the common C convention).
  • %p The void * pointer argument has to be printed in hexadecimal format.
  • %d Prints a decimal (base 10) number.
  • %i Prints an integer in base 10.
  • %u Prints an unsigned decimal (base 10) number.
  • %x Prints a number in hexadecimal (base 16) lowercase format.
  • %X Prints a number in hexadecimal (base 16) uppercase format.
  • %% Prints a percent sign.

• Variable argument list: Uses the stdarg.h library to handle a variable number of arguments.

Compilation

To compile the project, run the following command:

make

Then, create a file called main.c:

touch main.c

And put the following code inside main.c:

// Include the header
include "ft_printf.h"

int main(void)
{
      ft_printf("Personal printf Works\n");
      return (0);
}

Now, you're ready to compile the code. To compile, run the following command:

gcc main.c libftprintf.a && ./a.out

The output should be:

Personal printf Works
