Thread: pass array directly to new object

Hi, I have an object that takes an array as a parameter of the constructor:

Code:

class Foo {
public:
Foo(int array[]);

private:
int _array[];
}

If I want an array of the above type, and I want to pass in the array in one go:

Code:

Foo otherArray[5];
otherArray[0] = Foo({1,2,3,4,5});

How can I do that? It isnt happy?
I tried changing the array in the class Foo to an int* and then also passing the size, i.e:

Code:

Foo otherArray[5];
otherArray[0] = Foo({1,2,3,4,5}, 5;

but that didnt work either? It doesnt compile...

Thanks

A couple of things, first you can't define a zero length array, you need to specify the size of the array. Second since you defined a constructor that takes a parameter you no longer have a default no argument constructor so the following line is incorrect because it requires the default constructor.

Code:

Foo otherArray[5];

Have you considered using a std::vector instead of the array?

I suggest you post a small complete program that illustrates your problem.
