printf()

The printf project is a collaboration between Ziad Ammar and Ahmed Yasser, actual students of Software Engineering at Holberton School, were a function named "_printf" imitates the actual "printf" command located in the stdio.h library. It contains some of the basic features and functions found in the manual 3 of "printf".

_printf() is a function that performs formatted output conversion and print data. Its prototype is the following:

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

Where format contains the string that is printed. As _printf() is variadic function, it can receives n arguments that replace by n tags written inside the string.

The format tags prototype is the following:

If the program runs successfully, the return value is the amount of chars printed.

Specifier	Output
c	Character
d or i	Signed decimal integer
s	String of characters
%	Character

Examples

1. Printing the string of chars "Hello, Holberton":

2. Printing an integer number:

   • Use: _printf("10 + 10 is equal to %d.", 20);
   • Output: 10 + 10 is equal to 20.
