[Dev-C++] Beginner help

[Willz <moa...@nt...>]

I have just yeaterday started to tach myself programming in c++.I was =
wondering if after you have compiled a programe and run it how to make =
it saty on the screen to view it.

I know you can open up the dos prompt and drag it into the box,it then =
shows its path at the command line then one click and enter and it =
runs.But can it be run and displayed in dev version 4 to stay on the =
screen till you close the window down.


It is mostlikely an option but with all the terms new to me i aint sure =
off what it would be called .

Thanks all...

You could do

#include <stdlib.h>

then

system("PAUSE");

at the end of your main function.

Kevin.

Another common solution to this is a call to the function getc(), which =
waits for the user to press a key, before continueing.

For example:

int main(void)
{
  cout << "Hello World!\n";
  getc();
}

To use getc(), will require the stdio.h C library, I suppose a similar =
solution is possible with cin, the opposite to cout.  Also, the standard =
iostream header is require for cout/cin.

You can use cin.get()

;)

[Dev-C++] ":" Operator

[<jp...@bo...>]

    Recently I decided to start learning C++ again. When I was taking a=20
look at VC++, I've found a piece of code that I have no idea of what it=20
does:

    aView::aView() : m_rectEllipse(0,0,2000,-1000){...}

    My doubt is at the single ":" operator. I thought it was used just=20
when I'd like to invoke the constructor of a base class through a=20
derived class. But in this case, in the part of the code I've ommited=20
here, m_rectEllipse is a CRect object, member of the aView class. Is=20
there another way to use the ":" operator that I missed?

    Never mind... I've found it on the net. It can be also used to=20
initialize contained objetcts of a class... Is that right?

[Nathan S. <cat...@do...>]

Yes the ':' operator in this instance just defines the initialization lis=
t.
Init lists can be used on any form of constructor to my knowledge, not ju=
st
for composed classes. Hence, they can be used to initialize data members =
of
that object.

[Graham D. <g.d...@nt...>]

It's not an operator, it starts the member intialiser list. This can be 
used to intialise both the base class and member variables. e.g.

class bar
{
public:
    bar(int i) : barmember(i) {}
private:
    int barmember;
};

class foo : public bar
{
public:
    foo(int i) : bar(i), foomember(10) {}
private:
    int foomember;
};
