470: Highlights

• If you want a program to decide which of many alternative statements to evaluate, then instantiate the following pattern:

  switch (integer-producing expression) { 
    case integer literal 1: statements for integer 1 break; 
    case integer literal 2: statements for integer 2 break; 
    ... 
    default: default statements 
  } 
  

• In switch statements, you can omit the keyword default: and the default statements.
• In switch statements, the integer-producing expression can produce a value belonging to any of the integral data types, including the char data type.
• In switch statements, once embedded-statement execution begins, execution continues up to the first embedded break or return statement, or to the end of the switch statement, whichever comes first. Bugs emerge when you forget to pair case keywords with break or return statements.
