Computer Programming - 7.1 to 7.11

Describe the format for declaring pointers

variableType *pointerName;

variableType *pointerName, nonPointer;

Describe the initializing of a pointer variable

Describe what happens when & and * are used on a pointer

• The value of the pointer is used

  • Regardless of the order of * and &

Describe the template for writing a function header that takes a pointer as a parameter

outputType functionName(variableType *pointerName);

Use pass-by-reference to cube a number

Describe the declaration of Non-constant pointer to Non-constant data

Describe the declaration of Non-constant pointer to constant data

Describe the declaration of a constant pointer to non-constant data

Describe the declaration of a constant pointer to constant data

Write code to bubble sort an array using pass-by-reference

Describe the template of using sizeof

• sizeof( variable/structure type)

• returns number of bytes

• only works on arrays inside the scope where the array is defined

  • therefore arrays passe to a function will not work with sizeof

Describe the operations that can be done on pointers

Describe the addition of integers to a pointer

Describe the subtraction of pointers by integers

Describe the incrementation and decrementation of pointers

Describe the subtraction of pointers from one another

Describe assigning pointers to one another

Describe the implementation of an array of strings using a template
