    Question A question on Pointers & Structs

    Im studying for my final on c++ and the instructor gave us some questions to study that will help us in the final exam. There is this one question that I didnt know how to solve. Here it is:
    ==========
    Declare a pointer variable "structPointer" and initialize it to point to a struct variable called "newPhone", of type "Phone", that has three int fields called "country", "area" and "number". Also write the declaration of the "Phone" type. Then write assignment statements to indirectly store the values 1, 888, 5551212 into these fields.
    ==========

    It seems simple and I tried to do it but sometimes I just get lost. Can someone please solve this for me. The final is tomorrow and Im probably going to need to know this.

    I'm just guessing but...... something like this maybe?

    Code:
    struct Phone
    {
    	int country;
    	int area;
    	int number;
    };
    
    int main()
    {
    	Phone newPhone;
    	//...
    	Phone *structPointer = &newPhone;
    	structPointer->country = 1;
    	structPointer->area = 888;
    	structPointer->number = 5551212;
    	//...
    
    	return 0;
    }
    The question was kind of ambiguous, so this might not be what they meant.

    I find it kinda ironic that someone who has "do your own homework" in their sig gives out the answer like that!

    If you program in C++, you need Boost. You should also know how to use the Standard Library (STL). Want to make games? After reading this, I don't like WxWidgets anymore. Want to add some scripting to your App?

    I was so close. The Phone type thing got me lost. The problem is we did things like this in class but I always forget the dumbest things.

    Thank You

    The way I figure it... his final is tomorrow. He's gonna fail regardless of what I do.

    Nah, just kidding. He just wants to see some work before he writes a test. That's fine with me, especially since the question was written so ambiguously, that the tax codes make more sense.

    As such, I have no idea if what I provided is even correct.
