Problem with dynamic memory

[krutuk]

This program hasn't been done yet. I don't know what should I do. Here is the code

#include <iostream>
#include <cstdlib>

using namespace std;

double** Cr_Arr();

int nr, nc;

int main()
{


    return 0;
}

double** Cr_Arr();
{
    double **pmat;
    cout<<"Matrix dimensions - ";
    cin>>nc>>nr;
    pmat=new (double*)nr; 
    if(!pamt)
        return NULL;
}

The compiler has writen:
Error: can't convert 'double**' to 'double*' in assignment
Error: expected ';' before 'nr'

Shall be

pmat = new double * [nr];
