Instead of this:
I need something that combines them, like this (even though this code doesn't work):Code:case 'r': { Mufftastic code. } case 'R': { Same mufftastic code. }
Can anyone offer any advice? Examples, even? Thanks!Code:case 'r' || 'R': { Mufftastic code. }
Code:case 'r' : case 'R' : //insert code here break;
Code:>+++++++++[<++++++++>-]<.>+++++++[<++++>-]<+.+++++++..+++.[-]>++++++++[<++++>-] <.>+++++++++++[<++++++++>-]<-.--------.+++.------.--------.[-]>++++++++[<++++>- ]<+.[-]++++++++++.
There is such a thing as "fallthrough":
Which is why break is so important in cases, normally.Code:case 'r': /* Nothing here, so we "fall through" to the next case */ case 'R': /* Code. */
Or you could even do
Consider this, if you have a lot of case letters to choose from. A missing fall-through case would be a hard bug to spot in a sea of other cases.Code:switch ( toupper(ch) ) { case 'R': // also case 'r' from the toupper() in the switch }
But if you also have
then you will need to use the fall through style for any letters where case does not matter.Code:switch ( monty ) { case 'X': // do something case 'x': // and now for something completely different }
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
I never did think about doing such a thing. Thanks, everyone!
If you want a little fun with switch case, to illustrate the issue...
Code:#include <stdio.h> int main (void) { int i; for (i = 0; i < 5; i ++) { switch(i) { case 0 : printf("The "); case 1 : printf("fast "); case 2: printf("feline "); case 3: printf("flies "); case 4: printf("farthest"); case 5: printf("\n"); } printf "\n"); } return 0; }
