C++ Inheritance

[jlisec01]

Hello everyone, wasn't too sure if anyone knew any c++ here or not, but I'm having a problem with inheritance. Here is my problem:

I have my class, with private variables int and double, but if I want to initialize both with one of my constructors that has a parameter set to, int and int, how could I do that? I'll paste an example below:

class something {
public:
 void something(int, int);
private:
 int x;
 double y;
};
 
// and here how would I create a function of "something" to initialize x and y to the parameters int, int?

thanks for any help.

You mean just filling in the constructor?

You'd do something like (in the implementation file):

something::something( int x, double y )
{
  this->x = x;
  this->y = y;
}

Or were you asking another question ( the title seems to be misleading/contradicting? )

Hi there, thanks for writing me back,

the problem was that the private member variables are int and double, and I need to write a function that initialize both of those variables to the function with parameters int and int;

something::something(int a, int b) {
 
 // how can I initialize the double variable with an int parameter?
 
}

thanks for the help. (PS) Could I use the static cast?

Oh I see, yes you'd use a static cast, as in:

this->y = static_cast<double>(y);

I guess the title is not "correct" but would I use "this ->" ? or could I use:

something::something(int a, int b) {
 
 x = a; // int variable x
 static_cast<double>(y) = b; // double variable y
 
}

Thanks for your help I really appreciate it.

I much prefer m_ prefix for members to cut out the ambiguity (which is why I used this->)

c++ is a nightmare for web apps, too much care has to be taken to manage alloc/dealloc of memory...a memory leak on a server app can crash a server in jig-time...there are plenty more web-friendly alternatives such as perl/php/python all which support OO development
