Switch Case

Do not put spaces in the parenthesis of the switch declaration.

The curly bracket goes on the same line with a space after the closing parenthesis.

EXAMPLE: BAD:

switch ( variable ) {

switch(variable){

GOOD:

switch(variable) {

case is not indented.

Always put break unless you intend fallthrough. If you are falling through, put each case on seperate lines.

Always put a default case. default should always be the very last case, unless you are intentionally falling through with it.

Try to use enum's whenever possible.

EXAMPLE: BAD:

case A:
  case B: case C: 
  
  break;
default:
case D: 
  
  break;

GOOD:

case A:
case B:
case C:
  
  break;
case D:
default:
  break;

When using C++17 always include the [[fallthrough]] attribute when falling to the next block
