I have this function for reading input using `getch()` ```c char *TypingFunction(int min_ascii, int

char *TypingFunction(int min_ascii, int max_ascii, int max_len)
{
    int chr = 0, index = 0;
    char *num_str = (char *)malloc(max_len) + 1;

    memset(num_str, 0, max_len); // Clear string
    while (chr != 13)             // Loop while enter isn't pressed
    {
        chr = getch();
        if (chr == 27)
        {
            break;
        }
        if (chr == 8) // Backspace
        {
