CPP code syntax legality?

[OgreProgrammer]

I am away from my compiler for a few days and I had an idea. I am wondering if this is problematic. Can the default come first? text is set by a mouse click, so its only possible to be one of those four types.



switch(text) {
default : type = REGION_ACTOR_FILLED;
case "Normal" : type = SPRITE;
case "Canvas" : type = CANVAS;
case "Wire Frame Region" : type = REGION_ACTOR;
}


Googling switch case doesnt seem to cover that.

The default can come first, but typically most programmers put it last.

As for your case values, switch() will not work with a string. To do what you want, you will need to manually define the if/else blocks.

P.S. In the future, should you use switch/case statements, don't forget the 'break' after each case.

Some compiled languages support matching strings in case statements, C/C++ is not one of those languages - although I have seen some wild and wonderful ways to hack it on.

One notable except I've seen (from xchat)


switch (code) {
case CHR('W','O','R','D'):
/* do stuff */
break;
}


Where CHR() is a macro that does some magic along the lines of:

return (a << 1) + (b << 2) + (c << 4) + (d << 8);



On a side note, you should really use break; else the statement will fall through and run the code beneath too. :)

Yeah, I took them out to simplify.

Thanks for help people.
