This project is for replicate the C standard library printf() function
What you should learn from this project:
- Application of variadic functions
- The complexities of printf function
- How to use git in a team setting
- How to work in a team
Printf function with the printing features of characters (c), strings (s), % (%), octales (0), hexadecimals ( x and X), string in rot13 and we also did a binary function (b)
We create a mini function printf like that of the C language, we document with the book the secrets of printf. We use the putchar function of the syscall writer function. and we work with data structures, with a structure called from the main.h
- All codes will be compiled this way: gcc -Wall -Werror -Wextra -pedantic *.c
| file | Description |
|---|---|
| main.h | A file for call to prototypes and structurs |
| _putchar.c | A file for call to syscall (writer) putchar print in _printf |
| _printf.c | A file for call base structur from main.h |
| print_chars.c | A file for printing a char, string, Ascii value in uppercase, string and nonprintable character ascii values also string in reverse |
| print_hex.c | A file for print hexa numbers and also an address |
| man_3_printf | A file man type for printf function |
| print_rot13.c | A file for print encripted numbers in rot13 |
| print_numbers.c | A file for print integers and decimal |
| handle_flags.c | A file that finds the flag function, modifier function also clears struct fields and reset buf |
| print_unsigned_int.c | A file for print an unsigned in in decimal notation, takes an unsigned int and prints it in octal notation, takes an unsigned int and prints it in binary notation. |
int _printf(const char *format, ...);
- Prints a string to the standard output, according to a given format
- ALl files were created and compiled on Ubuntu 14.04.4 LTS USING GCC 4.8.4 with the command
gcc -Wall -Werror -Wextra -Pedantic *.cAll files were linted for syntax and style with [Betty] - Returns the number of characteres in the output string on succes, -1 otherwise
- Call it this way:
_printf("format string", arguments...)where format string``` can contain conversion specifiers and flags, alog with regular characteres.
