ft_printf
A versatile and customizable formatted output function.
Description
The ft_printf project reimplements the standard C printf function.
The goal is to create a function capable of formatting and printing different types of data, supporting multiple conversion specifiers, flags, and modifiers. This project deepens the understanding of variadic functions, parsing, and formatted output.
Features
Function Prototype
int ft_printf(const char *, ...);
Supported Conversion Specifiers
%c- Character%s- String%p- Pointer address%d/%i- Signed integers%u- Unsigned integer%x/%X- Hexadecimal (lowercase/uppercase)%%- Percent sign
Supported Flags

ft_printf("Printed %d characters.\n", count);
return (0);
}
int main(void)
{
