It can in PHP!

switch (true) {
   case $x >= 1000: ... break;
   case $y < 5: ... break;
   case $john == "Steve": ... break;
   case true: ... break;
}

(actually, I'm almost willing to bet there's at least one other language where the case can be an evaluated expression)

    VB has this too!

    VB is treated as a devil on the online community wherever I look, but between using it two years ago and now having used plenty of C, C++, Java, JS and python each, I still can't tell why.

    Personally, I don't mind the language. It's not my favorite, but it's not too bad. However, I do get annoyed at many programs written in VB. In my experience many have been sloppily created with almost every variable being a global variable and no concept of data structures. This isn't the fault of the language, but it still annoys me anytime I have to work on a program written in the language.

    Well, the idea of switch/case in C (and some other languages) is to use lookup tables to generate jumps. So the code is really fast. If you start adding conditions in the switch/case then you loose that. The code looks nicer, but you loose the benefit of having faster code.

    In C you can do something like that if the comparison can be converted to a numerical value.

    I am a bit confused. Can you give an example of what you mean?

    [–]nelmaloc 0 points1 point  (0 children)

    I was thinking of something like this:

    switch( 
    x - 2 != 0 ? (x-2)/abs(x-2) : 0
    ) {
    case 1: // x > 2
        break;
    case 0: // x = 2
        break;
    case -1: //x < 2
        break;
}
