# ft_printf
### Custom printf Implementation
This project is a simplified implementation of the printf function, replicating specific format specifiers for educational and practical purposes. The goal is to understand and reconstruct the core functionalities of the widely-used printf function in C.
## Features
The following format specifiers are supported:
Supported Specifiers
- %c: Prints a single character.
- %s: Prints a string of characters.
- %p: Prints a void * pointer argument in hexadecimal format.
- %d: Prints a decimal (base 10) number.
- %i: Prints an integer in base 10.
- %u: Prints an unsigned decimal (base 10) number.
- %x: Prints a number in hexadecimal (base 16) format.
- %%: Prints a percent sign.
### Example Code
```c
int main() {
ft_printf("Character: %c\n", 'A');
ft_printf("String: %s\n", "Hello, World!");
ft_printf("Pointer: %p\n", (void *)0xDEADBEEF);
ft_printf("Decimal: %d\n", 123);
ft_printf("Integer: %i\n", -456);
ft_printf("Unsigned: %u\n", 789u);
ft_printf("Hexadecimal: %x\n", 0x1A3F);
ft_printf("Percent Sign: %%\n");
return 0;
}
