C - printf team project

Synopsis

This is a simple implementation of printf function that formats and prints data.

Description

The _printf() function produces output according to a format which is given. The functions will write output to stdout, the standard output stream. The function returns the number of characters printed (excluding the null byte used to end output to strings) when successful. format is a character string. The format string is composed of zero or more directives. The conversion specifiers handled in this project include:

• %c: Prints a single character.
• %s: Prints a string of characters.
• %d: Prints integers.
• %i: Prints integers.
• %b: Prints the binary representation of an unsigned decimal.
• %u: Prints unsigned integers.
• %x: Prints the hexadecial representation of an unsigned decimal in lowercase letters.
• %X:Prints the hexadecial representation of an unsigned decimal in uppercase letters.
• %r: Prints a reversed string.

mandatory

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)
• 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. You need to handle the following conversion specifiers:

• c
• s
• %
• You don’t have to reproduce the buffer handling of the C library printf function
• You don’t have to handle the flag characters
• You don’t have to handle field width
• You don’t have to handle precision
• You don’t have to handle the length modifiers

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

advanced

Handle the following custom conversion specifiers:

• b: the unsigned int argument is converted to binary

alex@ubuntu:~/c/printf$ cat main.c #include "main.h"

/**

• main - Entry point
• Return: Always 0 */ int main(void) { _printf("%b\n", 98); return (0); } alex@ubuntu:/c/printf$ gcc -Wall -Wextra -Werror -pedantic -std=gnu89 main.c alex@ubuntu:/c/printf$ ./a.out 1100010 alex@ubuntu:~/c/printf$

4. Nothing in fine print is ever good news

5. My weakness is wearing too much leopard print

advanced

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)**

alex@ubuntu:~/c/printf$ cat main.c #include "main.h"

/**

• main - Entry point
• Return: Always 0 */ int main(void) { _printf("%S\n", "Best\nSchool"); return (0); } alex@ubuntu:/c/printf$ gcc -Wall -Wextra -Werror -pedantic -std=gnu89 main.c alex@ubuntu:/c/printf$ ./a.out Best\x0ASchool alex@ubuntu:~/c/printf$
