I'm a programming student in my first C++ class, and recently we were encouraged to write a simple recursive function to find the first occurrence of a substring in a given string. If found, it returns the index. If the substring is not found, the index_of() function should return -1. We are encouraged to use a helper function that ta...
I'm trying to create a singly linked list from an input text file for an assignment. I'm trying to do it a little bit at a time so I know my code is not complete. I tried creating the head pointer and just printing out its value and I can't even get that to work, but I'm not sure why. I included the struct, my create list, and print l...

I'm basically trying to create a linked list from a text file and add a new member every time the words are different, and increment the count if the words are the same (hw assignment). I thought I did it correctly, but it seems to add a member no matter what. I'm wondering if I'm traversing the list incorrectly while I search? Here i...

The question: Assume that cache memory is ten times faster than DRAM memory, that DRAM is 100,000 times faster than magnetic disk, and that flash memory is 1,000 times faster than disk. If it takes 2 microseconds while reading from cache memory, how long does it take to read the same file from DRAM, disk, and flash memory? Does th...

That being said, it's extremely open ended and we've had almost zero guidance as to how to even begin thinking about this problem (or parallel algorithms in general). I'd like pointers in the right direction and not a full solution. Any reading that could help would be excellent as well. I'm working on ...
