_printf()

The printf project is a collaboration between Halima Iyke - Oginah and Faith Ujunwa Ozoanieke, students of Software Engineering at ALX.

This function named "_printf()" imitates the actual "printf()" command located in the stdio.h library of C programming Language. 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.

_printf() is a variadic function, it can receives n arguments that replace by n tags written inside the string.

The format tags prototype is the following:

%[flags][length]specifier

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