Selection (IF) Statements

• Selection (or conditional execution)
  • Three types (single-, two-, or multi-alternative)
  • Single:  if (expression) action
  • Two:  if (expression) action else action
  • Multi:  if (expression) action else if (expression) action else if (expression) action else action
    • The multi version appears often enough that it has it's own special form:  The switch statement
    • Example:  switch (switchexpr) { case caseexpr: action case caseexpr: action }
  • Example:  See selection.cpp
