  1. In Topic: Default case in switch statement

    Posted 21 May 2015

    how to make the program automatically choose the default case in a switch statement after a certain amount of time has passed with no user input

    So, based on that, you need to keep track of the time passed (C++11 Chrono). To be able to do that while you are waiting for user input, you should take a look at multi-threading. I am not sure if doing so is the right thing for you right now, it might be too advanced if you are not much familiar with the standard library.

    Edit: almost forgot! You need break; for the default case too! Although right now it's not any useful for reaching your goal.
  2. In Topic: Substring Printing using a For loop

    Posted 19 May 2015

    You should pay attention to the way index numbers are considered in C++. They start from 0.
    So, if you have a string with 4 characters... what are the valid indexes?
  3. In Topic: Moving forward in C++

    Posted 15 May 2015

    Use one of the C++ GUI libraries assuming you understand the language good enough. I can't emphasis this more, find a good library that is actually made for C++. You can always use C libraries in C++ but for your situation, it's not a good idea; it ruins your coding habits because the two languages are not the same. In fact, the latest C++ standard almost feels like a new language by itself.

    Here's my story:
    I have worked with Qt before for a time-series data forecasting project. First, I wrote the back-end (which means I used CLI at first) and did as much testing as possible. Then, I brought that into a Qt project and wrote the front-end GUI for it. For learning Qt, I used this book. However, a new version of Qt came out and this book is for the previous version! There are also tons of tutorials that you can find.

    You can find a project you like, and develop a front-end GUI for it. Or even better, make a front-end for one of your own projects.
  4. In Topic: Classes in multiple files

    Posted 13 May 2015

    Quote

    cout << "F**k classes in seperate files";
    

    How could you say such a thing? :o

    LOL! I understand the frustration, but you will see the benefit later if you continue to work with C++ on a larger project :)
  5. In Topic: Initialization of dynamic memory in c++

    Posted 13 May 2015

    Let's take a look at what you are doing in this loop:
    for(int i =0; i <10; ++i) {
        *x = 10;
        x++;
    }
    

    You are iterating over the dynamic array. However, you are updating the pointer each time to point to the next element of the array. So, when this loop is finished, x is not pointing to the beginning of the array anymore!
    Right after it, you have another loop to display the results:
    for(int i = 0; i < 10; ++i) {
        std::cout<<i<<" is "<<x[i]<<std::endl;
    }
    

    What does x[i] mean? It means the i-th element of the array, starting from where x points to. However, you have changed x and now it does not point to the beginning of the array anymore! So this second loop goes out of bounds of the array.
    You have the answer in your own code. Change the first loop and make it access the array just like you did with the second loop:
    for(int i =0; i <10; ++i) {
        x[i] = 10;
    }
    

    Spoiler


    Last but not least, you forgot to free the dynamic memory you have allocated. When you use new, you are responsible to free this memory whenever it's appropriate and you're done with it:
    delete[] x; //after you are done with x
