    Unhappy Homework due tonight! help please!!

    I'm learning C++ code in my engineering class, but my professor doesn't help, or explain. He just gives homework. Here is my assignment (it is split into 4 parts):

    1.) Write a program that reads a data file and determines the number of occurrences of each of the characters in the file; then, print the characters and the number of times that they occurred; if a character does not occur, do not print it (hint: use an array to store the occurrences of the characters based on their ASCII codes)


    The problem with the first one is that I don't know how to get the program to only print the characters that occur in the data file, mine prints all of the letters in the alphabet.


    So, ill post this now while i work on posting the other 3 parts.

    Here is the second one:

    "another simple code encodes a message in text such that the true message is represented by the first letter of each word; there are no spaces between the words, but the decoded string of characters can easily be separated into words by a person; write a program to read a data file and determine the secret message stored by the sequence of first letters of the words (hint: use the string class, and store the first letter of each word in a character string)"


    that one i have done, except it prints the results vertically instead of horizontally, so if anyone can help me with how to fix that, i'd appreciate it.

    Stop printing newlines when you don't want them.

    Funny how you so desperately need help because your homework is due tonight. I really doubt it was assigned today. You should go talk to your profs when you're having trouble (or TAs who are sometimes nicer), and you should start programming assignments before the day it's due to allot time for unforseen difficulties and bugs.

    Are you serious, your prof won't meet with you? That's frakked up, man. I'd go talk to his department head about that. Professors are supposed to be available to help out students. Doesn't he have office hours?

    not necessarily... some professors are really stuck up about their level of education. they expect you to respect and live up to their level, or you're not 'good enough'...

    no, he met with me once before, for a previous assignment.. but that was a while ago. And when i ask him, he wont.. i e-mail him with questions, and he doesn't reply. It's his first year teaching though.. so.. he doesn't like helping very much

    well what questions are you asking him? we appreciate more targetted questions than "I don't know how to do this" type of questions... you need to at least tell us where you're stuck so we can help unstick you and send you along your merry way...

    That's their problem and not mine, and if I knew of a professor at my school who wouldn't meet with me to answer questions, I'd get a bunch of my classmates together and we'd all meet with the department head. If the problem didn't get resolved soon after that, I'd start calling for his termination in the department, in the school newspaper and anywhere else on campus where people would listen to me.

    No joke. Professors are teachers, and they ought to act that way. Any prof that can't handle that ought to find another profession.

    The hint to use an array in the first project should give it away for you.

    Create an array of 128 elements (0 - 127). Initialize all the elements to zero. Now think about what you can do with each element while you're reading in characters, and how you can tell which chars were used and which weren't.
