C

goto

  1. Must be defined within a function
  2. Each label in one function must have a unique name. It cannot be a reserved C keyword
  3. C has a separate namespace for labels, so you can use the same name for a variable and a label
  4. Must be followed by a statement. We call it a `labeled statement`
  5. Has function scope, Therefore the label:
    • Must have a unique name within that function
    • Is not accessible outside the function, where it was defined
