printf

This project is a pair project by collaborators Yemi and Pibo.

• Prototype: int _printf(const char *format, ...);
• Returns: the number of characters printed (excluding the null byte used to end output to strings) write output to stdout, the standard output stream
• format is a character string. The format string is composed of zero or more directives. See man 3 printf for more details. This function handles the following conversion specifiers:

Specifier	Description
c	Prints a single character. The argument must be an int that represents the ASCII value of the character.
s	Prints a null-terminated string (pointer to char).
%	Prints a literal percent sign (%). No argument is required.
d	Prints a signed decimal integer. The argument must be of type int.
i	Prints a signed decimal integer. The argument must be of type int.

Examples:

1. _printf("Let's try to printf a simple sentence.\n");
   prints "Let's try to printf a simple sentence", followed by a new line
2. _printf("This is a number: %d", 39);
   prints "This is a number: 39"
