Our first team project. We are creating our own printf function... How cool :)

Our printftwin imitates the printf function by performing formatted output conversions and printing out data to standard output stream with the prototype;

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

The format string is composed of zero or more directives: ordinary characters (not %), which are copied unchanged to the output stream; and conversion specifications, each of which results in fetching zero or more subsequent argu‐ments. Each conversion specification is introduced by the character %, and ends with a conversion specifier.In between there may be (in this order) zero or more flags, an optional minimum field width, an optional precision and an optional length modifier.

Conversion specifiers used include:

%d or %i: Print the argument as a signed decimal integer. %u: Print the argument as an unsigned decimal integer. %o: Print the argument as an unsigned octal integer. %x or %X: Print the argument as an unsigned hexadecimal integer (lowercase or uppercase, respectively). %f: Print the argument as a floating-point number in decimal notation. %c: Print the argument as a character. %s: Print the argument as a null-terminated string. %h: Specifies that the corresponding argument is of type short int or unsigned short int for integer specifiers %d, %i, %o, %u, %x, %X. %l: specifies that the corresponding argument is of type long int or unsigned long int for integer specifiers %d, %i, %o, %u, %x, X.

We also handled flags, field width, precision and length modifiers.
