C++ Programming help needed

You need a hierarchy of switches. The order should be based on Venn-diangram style possibilities or you can draw the classic logic diagram.

Something like

Code:

if (master = 0)
{
  if (gear = P)
{
   if (inside stuff) {}
   if (outsides stuff) {}
   if (dashboard stuff) {}//not necessarily in this order
}
}

Hmm okay! I feel like this could get very long and messy. Could you maybe give me an example of using a switch statement instead of nested if's?
