1.1 Basic C++

• For the most part, I assume you know this, If you have questions ask.
• Use whatever style you like, but be consistant.
• AND INDENT
• Dynamic memory
  • What do the following do?

  •  int a

  •  int * b 

  •  new int

  •  new int [10]

  •  delete a
    	  
     Write a program that will generate a random sized array of random integers (1-20 elements), and also an array of floats.
    	       
          

1.4 Functions

• Function Prototype
• Function Declaration
• Parameters
  • Variable
  • Value
  • Constant Variable
  • Return value or void.
• Write a function that takes an array of integers, the size of the array and returns the average of the values in that array.
• Overloading
  • Two functions defined with the same name but different argument lists overload that function.
  • example:

    void printArray(int ary[], int size);
    void printArray(float ary[]; int size);
    	       

  • implement these functions, and write two overloaded functions to find the average of the arrays.
  • We can also overload operators (we will look at this in a minute)

1.5 Classes

• Give us the abiliity to group data and functions together
• In our case, we need both the array and it's size.
• Plus functions to
  • Initialize
  • Average
  • Print the elements
  • Print the size
• Public, Private
• Constructors
• destructors
• Shallow copy vs deep copy.
• friend functions

  friend ostream& <<(ostream & out, ...);
  ...
  ostream & <<(ostream & out, ...) {
      out << data
      return(out);
  }
