int	ft_tolower(int c)
// The ft_tolower function takes an integer c as input, which represents a 
// character. It returns an integer representing the lowercase version of the 
// character.
{
	// The expression (c >= 'A' && c <= 'Z') checks if the character is within
	//  the uppercase range
    // If it is, the expression evaluates to 1, and ('a' - 'A') is added to 
	// the character's ASCII value to convert it to lowercase
    // If it's not an uppercase character, the expression evaluates to 0 and 
	// the original character is returned as it is
	return (c + (c >= 'A' && c <= 'Z') * ('a' - 'A'));
