Arrays

• C++ Arrays
  • Used for a collection of objects of like type
  • Declaration syntax:  BaseType ArrayName[SizeExpr] = {Initialization};
    • Examples
      • int A[10];
      • char letters[15];
      • float nums[5] = {3.0, 2.0, 4.55, 6.77, 0.332};
  • Scope and Initialization (arrayinit.cpp)
    • Initialization is optional, if not initialized then garbage values in array
    • Rules on initialization:
      • Global scope:  Automatically initialized to zero (or equivalent)
      • Local scope:  Not automatically initialized
        • Partial initialization
        • Full initialization
        • Implicit size
  • Search for smallest (find_smallest.cpp)
    • Demostrate program
    • Modify program to find position
