Write three short programs that implement the Bubble Sort, Selection Sort, and Insertion Sort algorithms. Each of these programs will read up to 1000 integers, sort them, and then print them in a formatted fashion.

Each program you write should read from standard input using input redirection. Input files for this assignment will contain a series of integers separated by whitespace.

The setup script will create the directory Assign1 under your csci241 directory. It will copy a makefile named makefile to the assignment directory and will also create symbolic links to a number of sample data files that you can use to test your programs.

You should assume that we will test your programs using data files other than the ones supplied as part of this assignment.

Using the makefile we give you, you can build one specific program or build all three programs. To build a single specific program, run the command make followed by the target name for the program that you want to build (bubble_sort, selection_sort, or insertion_sort). For example:

z123456@turing:~$ make bubble_sort

To build all three programs, run the command make all or just make.

Running the command make clean will remove all of the object and executable files created by the make command.

The data files are named random6.txt, random8.txt, random16.txt, etc., with the numeric part of the file name specifying the number of random values that the file contains.

You will write three files for this assignment:

• bubble_sort.cpp - This file should contain your solution that uses the bubble sort algorthm.
• selection_sort.cpp - This file should contain your solution that uses the selection sort algorthm.
• insertion_sort.cpp - This file should contain your solution that uses the insertion sort algorthm.

The three files will obviously contain a great deal of identical code.

The output should print 8 sorted numbers per line (of course the last line may have less than 8 numbers), nicely aligned in columns. Numbers should be right-aligned. Use the setw manipulator to pad numbers with leading spaces. Print a space between numbers and a newline character ( ) at the end of each line. The output should look like this:

z123456@turing:~/csci241/Assign1$ ./bubble_sort < random6.txt 19 61 75 88 90 98 z123456@turing:~/csci241/Assign1$ 

z123456@turing:~/csci241/Assign1$ ./selection_sort < random16.txt 7 15 15 20 30 37 42 52 53 56 58 63 65 74 78 89 z123456@turing:~/csci241/Assign1$ 

z123456@turing:~/csci241/Assign1$ ./insertion_sort < random25.txt 1 23 106 127 147 148 157 208 239 265 282 483 561 576 579 677 753 853 879 911 945 959 965 978 982 z123456@turing:~/csci241/Assign1$ 

Note that your programs must always supply a newline character at the end of each line, even if the last line does not contain 8 numbers. In other words, after running your program, the Unix prompt must always appear in the leftmost column of the screen. Output that looks like this is incorrect:

z123456@turing:~/csci241/Assign1$ ./bubble_sort < random6.txt 19 61 75 88 90 98z123456@turing:~/csci241/Assign1$
