[C++]

Learned something new today.

If you get the "jump to case label" error in g++. This is caused when you don't have brackets in a switch-case but are trying to instantiate variables within the case statement.

switch( num )

{

case 1:

int a;

...

break;

....

Bad.

switch (num)

{

case 1:

{

int a;

....

}

Good.
