C++ counting word occurence in a text file. I have everything written it just isn't working properly. We just learned dynamic memory so it's a bit confusing for me still. I have it to where I read in one word from the text file, call my countWords function, then increment entries to move on to the next word (we aren't allowed to do any processing in the input function). When using the debugger, the word being held in temp gets copied over to my words variable but it won't enter the loop to compare two words, it breaks at the _stricmp condition. Can anyone please explain why it is not currently working and/or point me in the right direction? Thank you so much!
