Task

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

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) 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 detail. Handles the following conversion specifiers: c s %

Task 1

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

Handles the following conversion specifiers: d i

Task 2

Just because it's in print doesn't mean it's the gospel

Man page for the function.

Task 3

With a face like mine, I do better in print.

Handles the following custom conversion specifiers:

b: the unsigned int argument is converted to binary

Task 4

What one has not experienced, one will never understand in print

Handls the following conversion specifiers: u o x X

Task 5

Nothing in fine print is ever good news

Uses a local buffer in order to call write as little as possible.

Task 14

Print is the sharpest and the strongest weapon of our party

Handles the following custom conversion specifier:

r : prints the reversed string

Task 15

The flood of print has turned reading into a process of gulping rather than savoring

Handles the following custom conversion specifier:

R: prints the rot13'ed string
