  1. Re: Overloading the = Operator for a Class

    There's no hard and fast rule. You can write:


    void exclass::operator =(const differentclass& right_hand_side);

    However, as Lindley mentioned, there has to be a reason for doing so.

    Also,...

    Poll: Re: Preference question about libraries

    I tend to use forward declarations if it would suffice. The reasons are exactly the same as what Lindley mentioned.

    Re: Parse C++ function

    Yes, I'm aware of what a function prototype means. However, what do you mean by parsing? Are you talking about identifying all function prototypes in a source file?

    Re: Little help

    Your function declarations are not compatible with their definitions. Your declarations should be:


    int randArray(int array[], int size);
    int dispArray(int array[], int size);
    int sortArray(int...

    Re: String manipulation

    If I understand this correctly, your professor wants you to evaluate an infix expression. He may at any point in time ask you to do the same for a prefix or postfix notation. Be prepared!

    IMHO, at...

    Re: PLease explain this syntax

    Correct me if I'm wrong, but I think the second one is an overload of the function call operator that returns the sum of the argument and the data member as an int. So, you could do something like...

    Re: Linked List Stack Pop() problem

    You are returning prematurely from the function. When the return statement is encountered, the program will exit the function and the rest of the statements will never be executed. This means that...

    With cin, a white space is a delimiter. So, what's happening here is that data is being grabbed from the input stream until a space is encountered. After the first cin, the variable name will contain...

    As a good rule of thumb, I always prefer prefix to postfix in C++.

    Re: New Help with a problem

    Umm... The limit for the inner loop should be N/2, not sqrt(N) since we are trying to find factors, not prime numbers.

    Re: Function and char problem

    You could try:

    std::cin.ignore(std::numeric_limits<std::streamsize>::max(), ':');
    std::cin >> miles;

    This will ignore all the characters upto the maximum size of the...

    Yes, I've always believed that for a developer to truly say he knows C++, he should have read and understood Effective C++, More Effective C++, Exceptional C++ and More Exceptional C++.

    You've met Scott Meyers? That's amazing! I wish I could meet Scott Meyers someday (and Herb Sutter ofc). :)

    Re: passing function

    I believe that you just need to include "boost/function.hpp" to use it. You should be able to find this file in the boost folder of your installation.

    "clear" on Unix or Linux is the equivalent of "cls" on DOS.

    Re: Iterator Question

    Btw, your code has a memory leak. You do a new in the getKeyValue() function and never do a delete on the pointer that's returned.

    I'd suggest not returning by reference at all, instead return by...
  25. Re: Working in DOS. How to Launch another App?

    You may not know the absolute path but you must know the relative path. For example, if lwhiz.exe is right next to myapp.exe, then your relative path is simply "lwhiz.exe". If your directory...
