CS12, Lab 5

Week of February 4-8

Topics:

· pointers and dereferencing

· using pointer arithmetic to access array elements

· passing pointers as parameters to functions

To do:

· Copy the files array.cpp and param.cpp

· save them into two new files, p_array.cpp and p_param.cpp.

· rewrite the code in each using pointers

· in p_array.cpp:

· instead of the array declaration, declare a pointer to int and allocate space for an array of ints accessed by your pointer.

· convert the rest of the code using pointer notation. Square brackets may not appear anywhere in your code except when allocating space for the array.

· compile and run array.cpp and p_array.cpp and verify that the output is the same.

· in p_param.cpp:

· declare two pointers to double and assign them to the variables pi and e.

· pass the pointers (instead of the variables) into the function power()

· convert the code of the function using pointers. Do not change the cout statement at the end of the main program.

· compile and run param.cpp and p_param.cpp and verify that the output is the same.

Extra Credit:

· Do all the works in the Linux environment. Use the makefile for compiling.
