  1. In Topic: Also Fibonacci Squence in C++ Array Reverse

    Posted 2 Sep 2014

    Start with
    int FibArray[MAX] = { 0 };
    so you have a properly initialised array.

    Next, only print the array AFTER you have done all the calculations. You're printing the whole array (junk and all), every time around the loop doing the calculation.

    The implementation isn't required to diagnose every programming error at the point of origin (of the error). The lack of a crash is not (nor can ever be) an argument for the correctness of the code.

    Very often though, you'll find that the crash has just been deferred to some later point in the code - where it will be that much harder to solve.

    1. Is this C or C++ (noting that one of your other threads is pure C++, and the other is some bastardised mix of C and C++).

    2. Do you have a mix of string constants, statically allocated arrays and dynamically allocated memory?

    3. What sort of operations are you going to perform on the completed strings u and v? strlen / strcat / strcmp / others?

    Don't lay pointless restrictions on our implementation suggestions.

    If you want a reasonably efficient implementation, then all the string fragments should have the same properties (eg. /0 terminated in malloc'ed memory). The more permutations you allow, the messier it all becomes. Start with one useful case and make sure the idea works before trying to optimise it further.
  5. In Topic: Explaination required

    Posted 1 Sep 2014

    Here are some things to do.

    1. Decide whether this is C or C++. You've included all C++ headers, but there is precious little which is C++ specific.

    2. Run the code with a variety of inputs to get the feel for what it does.

    3. Go through the code and replace all instances of that silly forn macro with proper code.

    4. Go through the code and try and figure out what each variable is for. If it seems to be something important, then give it a better name (in place of all those meaningless single letter identifiers).
