Too many characters in character literal - trying to check if my value is not within ASCII values '\0'

/*Visit only nodes with keys*/
    if(root.alpha != '\0'){

    }

as the title above says. How would I do this better? I'm trying to check if the character (root.alpha) is not within that spectrum. Thanks.

Solution

  • To check that the character is not within the range of the hexadecimal ASCII codes 48 and 92:

    if (root.alpha < 0x48 || root.alpha > 0x92) {
    // ...
}

    That is, not within range = less than the start or greater than the end.
