#include <iostream>  
        
#include <boost/scoped_array.hpp>  
        
using namespace std;  
        
int main () {  
    const int n (3);  
    Boost::scoped_array<int> PData (new int[n*n]);  
        
    int temp[9] = {0, 1, 2, 3, 4, 5, 6, 7, 8};  
        
    Pdata.reset (temp);  
        
    For (std::size_t i=0 i<n*n; ++i) {  
        std::cout << "pdata[" << i << "] =" << Pdata[i] <& Lt Std::endl;  
    }  
        
    return 0;  
}

Output:

Pdata[0] = 0  
pdata[1] = 1  
pdata[2] = 2  
pdata[3] = 3  
pdata[4] = 4  
pdata[5] = 5  
pdata[6] = 6  
pDa TA[7] = 7  
pdata[8] = 8
