As asked of course it just means how complex or complicated a piece of software is, but generally the term refers to the big-O performance of an algorithm. So for example, searching a string for a cha...

Friend-ness and reference vs value parameter semantics are completely disconnected issues. You use refernces if you want changes to the parameter to be visible at the call site, and use copy if not. I...

There is nothing really wrong with C++ anymore. The few reservations I had personally have been fixed with the latest C++11 standard: - C++ wasnt really designed for writing multithreaded application...

Compared to what? C++ is a potentially low-level, close to the metal language, so potential for performance, though perhaps not as much as assembler, conversely its quite hard to learn, and now a big ...

Structure: Initially (in C) a structure was used to bundle different type of data types together to perform a particular functionality. But C++ extended the structure to contain functions also. The major difference is that all declarations inside a structure are by default public. Class: Class is a successor of Structure. By default all the members inside the class are private.

Structure does support inheritance.

try out the following code.

#include<iostream>

using namespace std;

struct Base
{
    int A;
};

struct Derived:public Base
{
    int B;
    void display();
};

void Derived::display()
{
    cout<<endl<<"A = "<<A<<endl;
}

int main()
{
    Derived D;
    D.A = 111;
    D.display();
    getchar();
    return 0;
}

Try out private and protected inheritance as well. It works. :)

All data members of the class is by default private,
Whereas all data members of structure is by default public.

Beware, whatever is supported by a class is also supported by struct whether its inheritance, polymorphism, encapsulation, data hiding etc. etc. as of C++ 11. Only difference is, for a class default access specifier is private whereas for struct its public.
