Task 0

I'm not going anywhere. You can print that wherever you want to. I'm here and I'm a Spur for life

Write a function that produces output according to a format.

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

Returns: the number of characters printed (excluding the null byte used to end output to strings)

Task 1

Education is when you read the fine print. Experience is what you get if you don't

Handle the following conversion specifiers: "d" "i"

You don’t have to handle the flag characters, field width, precision, or the length modifiers

Task 3

Create a man page for your function.
