trainee-cpp-sort is a program that has been developed from the beginning and should be an imitation of the standard sort command. It was only developed for learning and testing purposes, so I cannot guarantee that it will work perfectly with a real complicated program.
quick sort and merge sort algorithm have also been added to the program, so that with various sort options you have ample opportunities to simplify your work.
To learn more about what they mean and what they are for, see the bunch of sort options below.
| short Options | long Options | Usage |
|---|---|---|
| -b | --ignore-leading-blanks | Ignore leading blanks. |
| -f | --ignore-case | Ignore case e.g (uppercase or lowercase) this would be ignored. |
| -n | --numeric-sort | Numeric sort from the lowest the highest. |
| -o | --output[ARG required] | Write result in FILE instead of standard output. |
| -r | --reverse | Reverse the result of sorting. |
| -R | --random-sort | Sort the keys using a random hash. |
| -u | --unique | Only output the first of several matches. |
| -q | --quick-sort | Use quick sort Algorithm. |
| -m | --merge-sort | Use merge sort Algorithm. |
| -h | --help | Display this help and exit the Program. |
First of all we have to compile our code and this is done by doing the command as follows ./build.sh. This will compile and build your code.
If ./build.sh doesn't work for you, you can try chmod +x build.sh and it should work now.
And the compiled code is saved in the cpp-sort file as machine code.
Now we can e.g. execute this command to sort the contents of the in.txt file numeric-sort.
content of in.txt file:
4
9
6
15
10
3
12
8
7
The output looks like this, if you run this command
./cpp-sort -n in.txt OR ./cpp-sort -n < in.txt.
3
4
6
7
8
9
10
12
15
if you would like to sort with quick sort or merge sort you only have to change a little bit when executing
the commands as follows./cpp-sort -q -n in.txt OR ./cpp-sort --quick-sort -n < in.txt
And we do the same with merge sort./cpp-sort -m -n in.txt OR ./cpp-sort --merge-sort -n < in.txt.
They all work like clockwork.
And if you want to store the sorted values in a new file, you only have to do as follows..
./cpp-sort -n -o output.txt in.txt OR ./cpp-sort -n --output output.txt < in.txt
then check the output.txt file.
I hope you have as much fun with it as I have when coding and would be very happy if you would develop the program further or if you could give me suggestions how I can do it even better.
