Automatic Variables

• Identifiers that represent local variables in a method (method parameters and variables declared in the method body) have automatic duration:
  • They are created when the block in which they are declared is entered.
  • They exist while the block is active.
  • They are destroyed when the block is exited.
• They are called automatic variables.
• Automatic variables must be initialized explicitly in the program before they are used in an expression.
