Primary LanguageC

Printf Function Project

The _printf function created will print formatted output analogous to the origin printf

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

Description

_printf was created as part of the Holberton School curriculum dealing with low level programming and it's overall mission to create engineers who understand peer learning/programming. Said function's capabilities are similar that of the printf found in the standard library and will be discussed below.

Examples

Character: _printf("%c\n", 'H'); Output: H

String: _printf("%s\n", "Holberton"); Output: Holberton

Decimal: _printf("%d\n", 10); Output: 10

Integer: _printf("%i\n", 10); Output: 10

Binary: _printf("%b\n", 10); Output: 1010

Unsigned Integer: _printf("%u\n", 10); Output: 10

Octal: _printf("%o\n", 10); Output: 8

Hexademical version 1: _printf("%x\n", 10); Output: a

Hexadecimal version 2r: _printf("%X\n", 10); Output:A

rot13: _printf("%R\n", "abc"); Output: nop

Reverse String: _printf("%r\n", "Holberton"); Output: notrebloH

String Hexadeximal: _printf("%r\n", "Holberton\n"); Output: Holberton\x0A
