Simplifying Boolean Expressions

Simplifying Boolean Expressions

Here are some examples of code that make me cringe. Can you figure out how to simplify them?

•    if ( box.contains( point ) ) then { // do nothing here   } else {        counter := counter + 1   }
  

•     if (box.contains( point )) then {
          boxGrabbed := true
      } else {
          boxGrabbed := false
      }
  

•     if ( boxGrabbed == true ) then { 
          ... 
      }
  

•     while { done == false } do { 
          ... 
      }
