I found a source code of Huffman Coding algorithm. After I read the code, I didn't see any problem. So I downloaded it, and tried to run it. But then, it doesn't run (compiling fine). Probably there is something I misunderstood about the instruction of author. Can you guys please help me pointing out the problem here? The instruction said that I'm supposed to put the file name in the command line, but when I did it nothing happened. Here is the link to source code. Please help me!
