Custom _printf Function Implementation

Overview

This project implements a custom _printf function, mimicking the behavior of the standard C library printf function with a subset of format specifiers.

Features

Support for multiple format specifiers Variable argument handling Robust error checking Lightweight implementation

Supported Format Specifiers

%c: Character printing %s: String printing %%: Percent sign printing %d: Decimal integer %i: Integer

Function Prototype

int _printf(const char *format, ...);
int _putchar(char c);
int print_char(va_list args);
int print_string(va_list args);
int print_integer(va_list args);
int print_percent(va_list args __attribute__((unused)));

## Key Components
 Main `_printf` function
 Helper print functions for each specifier
 Variable argument list management

## Usage Examples
```c
_printf("Hello, %s!\n", "world");        
_printf("Character: %c\n", 'A');         
_printf("Integer: %d\n", 42);            
_printf("Percent sign: %%\n");         

Error Handling

Returns -1 if format string is NULL Handles unrecognized specifiers by printing them literally

install

to install it you need to clone our repo : git clone ://github.com/georges479/holbertonschool-printf.git

Compilation

gcc -Wall -Werror -Wextra -pedantic *.c -o printf

Execute

./printf.c

Dependencies

<stdarg.h>for variable argument handling Custom helpe1r functions: _putchar() print_char() print_string() print_integer() print_percent()`

Limitations

Limited to specified format specifiers No floating-point number support Minimal error checking compared to standard printf

Potential Improvements

Add more format specifiers Implement width and precision modifiers Enhanced error handling Support for floating-point numbers

Environment use

operating system : Ubuntu 20.04 Language : C Compiler : gcc 4.8.4 Style Guidelines : Betty
