Trees are beautiful. Learn to love them!

just looking for a more efficient way of doing things. God forbid someone makes an advance in the CS field. Trees are easy but feel so clunky to me.

Algorithm: Huffman codes without a tree.

So my data structures teacher assigned us a project to generate the huffman codes for a file and I was thinking that I hate the implementation of trees. So I was wondering if it is even possible to generate huffman codes without using trees given the number the number of unique characters in a file ...

Re: The "IT DOESN'T WORK!" thread

Let me ask you again: Don't you have a debugger that allows you to step through the code? If you don't, why don't you try the following version of getstuff(): info getstuff(){ info Anon; if( fgets(Anon.Name,80,stdin) == NULL ){ printf("Reading Name failed!\n"); Anon.Name[0] = '\0'; } if( ...

Indeed what you have said is true and I have fixed it to test correctly.

Re: The "IT DOESN'T WORK!" thread

It may be that the error does have to do with this however. What does getstuff() do when it reaches the end of file before it reads all of its data, or even when it tries to read the very first bit of data? Does it ignore it, and try to allocate zero bytes to store nothing in? Or does it do somethi...

Re: The "IT DOESN'T WORK!" thread

Here's what I've noticed: 1)My guess is you're trying to allocate an array of info structs and put them in the memory pointed to by the parameter strux. This is not what will happen. Note that you have 3 copies of the same pointer: the one in your calling code that you pass into getstuff(), strux, ...
