Printf
This project requires you to write your own Printf
I have implemented these conversions
Conversion | Description |
---|---|
% | prints percent sign |
a | prints float in hexadecimal scientific notation |
b | prints int in binary |
c | prints char |
d | prints decimal |
e | prints float in various special ways |
f | prints float |
g | prints float in scientific notation |
i | prints integer |
n | prints number of bytes written at that point |
o | prints unsigned integer |
p | prints memory address |
s | prints string |
u | prints unsigned integer |
x | prints int in lowercase hexadecimal |
X | prints int in uppercase hexadecimal |
And these flags
Flag | Description |
---|---|
# | Alternate Form |
0 | Zero Padding |
- | Left Adjustment |
space | Space before positive number |
+ | + before positive number |
1-9 | Field Width |
. | Precision |
* | variable placeholder |
Todo
Implement %a correctly
Implement lenght modifiers Lqtjz
Bugs
plus and space prints an extra space in rare undefined cases
floats lose precision
g printing 1.0000 while it should just print 1
g giving the wrong return value in some cases
e giving the wrong return value in some cases
double check length modifiers "l" "ll" "h" "hh"\
Usage
- Simply clone or download the repository
- Run
make
in the cloned directory - You can include the libftprintf.a in your own program
Tester
Todo
- check for -Wall -Werror -Wextra
- Add Infinity and NAN tests
- Harder checking on %n
- check with 2 conversions 1 correct and the other wrong?
- add strings with variables without any arguments
Usage
- Download test.sh and the tests folder to your printf directory
- Make the file executable
chmod +x test.sh
- Run
./test.sh
to start the test
