Project: LZW Compress
Introduction:
LZW stand for "Lempel–Ziv–Welch". It is a universal lossless data compression algorithm which is widely use in compressing software. It is widely used in image compress and Unix file compress. Here is a project example of LZW compressing written by c++. Here's the link for more details: https://codereview.stackexchange.com/questions/86543/simple-lzw-compression-algorithm
Basic Compile Command:(Linux)
g++ -std=c++0x lzw.c -o lzw
To Execute Projet
- Compress file:
./lzw -c file.txt
- Decopress file:
./lzw -d file.txt
Profile
We have compress and profile for 3 different size files. The runtime for each is shown below:
To see runtime for each function, see below:
Here is graphic:
Float profile:
Here is the float profile sample for compressing file which has size 54.3MB, float profile is changed to .txt and is simplified)
Project: Grep - Count Keyword in File
Introduction:
On the Linux system, we are very familiar with the Grep command. This is a similar project to that. But this one is more simple. It just counts how many times the keyword appears in the file. After compile the program, we run it as a command like this:
