printf

A replication of printf function built by Lawal Aremu and Obam Olohu as ALX project.

Introduction

Rebuild of the standard printf function in C. Our project required a function capable of printing with the %d, %c, %s, and %% specifiers to standard output. printf returns the number of characters printed (excluding the null byte at the end of strings). We were not asked to handle flag characters, field width, precision, or length.

Supported Format

TYPE - OUTPUT

c - Single character

s - String of character

r - String in reverse

R - String in rot13

d - Integer in decimal

i - integer

% - Percent sign

x - Lowercase hex(loervase)

X - Uppercase hex (unsigned)

b - signed binary

o - signed octal

u - unsigned integer

p - pointer address

Examples

Character: printf("%c", A); Output:: A

String: printf("%s", This is a string!); Output: This is a string!

Integer: printf("%i", 8); Output: 8
