constructor's parameters

[Gregor Pavlic]

Hello...

I created an object from a class... Inside this object I want to create an array of objects of another class, but with different parameters... What is the syntax to pass parameters to a constructor??

Thanks...

Just like a normal function:

class Foo
{
public:
Foo(int, float, char, whatEverElseYouNeed);
}

Foo::Foo(...)
{
//Code
}

First class header file:

#ifndef ONE_H
#define ONE_H


class One
{
    public:
        One(int a, int b);
    private:
        int x;
        int y;
};

#endif // ONE_H 

First class cpp file:

#include "One.h"

One::One(int a, int b)
:   x(a), y(b)
{
}

Second class header file:

#ifndef TWO_H
#define TWO_H
#include "One.h"

class Two
{
    public:
        Two();
    private:
        One one_object[2];
};

#endif // TWO_H 

Second class cpp file:

#include "Two.h"
#include "One.h"

Two::Two()
:   one_object[0](1,1),
    one_object[1](2,2)
{
}

The second class cpp file has an error...
Please help...

You can't use the initialization list to initialize arrays. You'll have to stick it in the constructor's body.

[Zhuge]

You can't call a non-default constructor for arrays at all. The objects are all default-constructed when the array is created.

struct A
{
    A( int ii, double dd )  : i(ii), d(dd) {}
    int i ;
    double d ;
};

struct B
{
    B() : array{ { 1, 2.3 }, { 4, 5.6 }, { 7, 8.9 }, { 0, 0 } } {}
    A array[4] ;
};
