The printf project is the first group project for the ALX SE course. The objective was to recreate the printf function provided in standard library with some custom specifier using all the knowledge gained from all previous projects and to develop our team working skills. Listed below are the tasks associated with this project.
Listed are the tasks of this project and links to the relevant files.
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.
- Specifiers:
- c: characters
- s: strings
- %: modulus
- Return: The number of characters printed.
- Handle the following conversion specifiers:
- d: decimals
- i: integer
- Handle the following custom conversion specifiers:
- b: the unsigned int argument is converted to binary
- Handle the following conversion specifiers:
- u: unsigned integer
- o: convert from decimal to octal
- x: convert from decimal to hexadecimal in lowercase
- X: convert from decimal to hexadecimals in uppercase
- Use a local buffer of 1024 chars in order to call write as little as possible.
- Handle the following custom conversion specifier:
- S: prints the string
- Non printable characters (0 < ASCII value < 32 or >= 127) are printed this way: \x, followed by the ASCII code value in hexadecimal (upper case - always 2 characters)
6. How is the world ruled and led to war? Diplomats lie to journalists and believe these lies when they see them in print:
- Handle the following conversion specifier: p
- Handle the following flag characters for non-custom conversion specifiers:
- '+'
- space
- '#'
- Handle the following length modifiers for non-custom conversion specifiers:
- l
- h
- conversion specifiers to handle: d, i, u, o, x, X
- Handle the field width for non-custom conversion specifiers.
- Handle the precision for non-custom conversion specifiers.
- Handle the 0 flag character for non-custom conversion specifiers.
12. Every time that I wanted to give up, if I saw an interesting textile, print what ever, suddenly I would see a collection:
- Handle the - flag character for non-custom conversion specifiers.
- Handle the following custom conversion specifier:
- r : prints the reversed string
- Handle the following custom conversion specifier:
- R: prints the rot13'ed string.
- All the above options work well together.
