This version of printf recreates the standard printf function. It's built to have all of the same basic functionalities as printf in the standard library, with a few additional capabilities. Printf is a function that takes in a format string, prints it to the standard output, and acts on format specifiers to print their respective arguments.
| Format Specifiers | Data Type |
|---|---|
| %i, %d | Prints a signed decimal value |
| %c | Prints a character |
| %s | Prints a string |
| %S | Same as (s) but prints unprintables as hex codes (32 = \x20) |
| %o | Prints a unsigned int in octal |
| %u | Prints an unsigned int in decimal |
| %b | Prints an unsigned int in binary |
| %x | Prints an unsigned int in hexadecimal with abcdef |
| %X | Prints an unsigned int in hexadecimal with ABCDEF |
| %r | Prints a string in reverse |
| %R | Prints an string after encoding in Rot13 |
| %p | Prints the address of a pointer in hexadecimal |
| %% | Prints a modulo |
- Clone this repository into your git. It contains all of the necessary components to make printf fully functional.
- Include the "holberton.h" header file in the programs that you want to use printf with.
- Execute _printf() as you would with a printf() function. Type the string that you want printed within the parentheses enclosed in double quotes. For format specifiers type a '%' sign followed by the character corresponding to the format specifier that you want to implement. Follow your double quoted string with a comma, and then a list of args to be called in the place of the specifiers.
For example: "_printf("Hello %c", "World")"
Will produce a string into the output that says: "Hello World"
