# ft_printf

A custom implementation of the C standard library printf function with support for basic format specifiers and flags.

## Overview

This project recreates printf's core functionality without using the buffer management of the original printf. It handles the most common format specifiers and formatting flags.

## Features

### Format Specifiers

| Specifier | Description |

|-----------|-------------|

| %c | Single character |

| %s | String of characters |

| %p | Pointer address in hex |

| %d | Decimal (base 10) integer |

| %i | Integer in base 10 |

| %u | Unsigned decimal integer |

| %x | Hex integer (lowercase) |

| %X | Hex integer (uppercase) |

| %% | Percent sign |

### Flags

| Flag | Description |

|------|-------------|

| - | Left-justify within field width |

| + | Force plus/minus sign |

| (space) | Space if no sign |

| # | 0x/0X prefix for hex |

| 0 | Zero padding |

| . | Precision |

| width | Minimum field width |

## Usage

```c

#include "ft_printf.h"

int main(void)

{

    // Basic string

    ft_printf("Hello %s!\n", "world");

    

    // Multiple formats

    ft_printf("Num: %d, Hex: %x, Char: %c\n", 42, 42, 'A');

    

    // Using flags

    ft_printf("Padded: %05d\n", 42);

    ft_printf("Left-aligned: %-10s\n", "text");

    

    return (0);

}

```

## Notes

- Buffer management is not implemented as per project requirements

- All memory allocations are properly handled and freed

- The project follows 42 school's coding standards
