What's wrong with this?

Hi,

Getting to grips with new operator.

What is wrong with the following code:

#include <iostream>

using namespace std;

void main()
{

	x = new double[200];


	cout << "x has size " << sizeof(x) << " and has value of %f" << x << endl;

}

Cheers

still need to declare a variable

double *x = new double[ 200 ];

no data type sets x to an int/undefined?? and sizeof(x) is returning 4 most probably ( 32 bits ) or 8 for 64-bit OS

Not an int. 'x' is undefined, so speculating the value of sizeof is pointless.

Don't forget to
delete [] x;
afterwards.

Also, main should return int.
You might also want to check up smart pointers.
