CS 4448 - Spring 1998
Object-Oriented Programming and Design
Homework #8

Due on Thursday, April 9 at the start of class.

You must print out your code and the output from running the program. You DO NOT need to mail me the code. The various tests can made into several separate programs or put into one. I leave that up to you. Note: on nag the stl include files can be found at /tools/cs/gcc/include/g++

Code re-use via Templates

This assignment uses the STL. Putting the command "using namespace std;" in your program should save on typing and be useful.

Using iterator.h

Use two simple iterators. Get 2 numbers from the user and then output the result. istream_iterator must be used for getting input and ostream_iterator for the output.
The program output should be as follows.


Enter two integers: 12 25
The sum is: 37

Use an appropriate template from the STL

Make a class that contains a list of doubles. Doubles can be added to the front or back of the list. They can also be removed from the front or back of the list. First you will add 2.2 to the front then 3.5 to the front and finally 1.1 to the back. Then print the contents using a for loop. Then remove the value from the front and print the new contents. Finally change the value in position [1] to 5.4.
The program output should be as follows.


values contains: 3.5 2.2 1.1
After popping the front values contains: 2.2 1.1
After values[1] = 5.4 values contains: 2.2 5.4

Use the vector class and numeric.h and algorithm.h

Create a vector of integers. Initialize the vector to {100, 2, 8, 1, 50, 3, 8, 8 ,9, 10}. First output the vector using the copy function. Then perform a sort and print the output. Then random_shuffle on the vector and then print out the vector again. Then use count_if, min_element, max_element, and accumulate to generate the output that follows.


Some code you can use for the last two parts of the output
You must write outputSquare.
for_each(v.begin(),v.end(), outputSquare);
.....
You must write calculateCube.
transform(v.begin(),v.end(), cubes.begin,calculateCube);
Then do output of cubes.

The program output should be as follows.
