Re: [Dev-C++] Need help translating from java to c++

[<qa...@ho...>]

I found the way to create a multidimensional array with the size set at=
 runtime.

The code is, in my case:

---

int row =3D atoi(argv[1]); // nbr of rows in the matrix
int col =3D atoi(argv[2]); // nbr of columns in the matrix
vector< vector <double> > v(row, vector<double>(col)); 

---

It now works fine to set the values with for instance

---

for(int i=3D0; i<row; i++)
    for(int j=3D0; j<col; j++)
        v[i][j] =3D (double) (i+j) / 3;

--

Now when this matrix is set I'd like to pass it on to a function:

---

void printMatrix(vector v){
 for(int i=3D0; i<v.size(); i++){
  for(int j=3D0; j<v[0].size(); j++)
   cout << v[i][j] << " ";
  cout << endl;
 }
}

---

but the compiler complaints.

How shall I do to be able to pass it on to the function?

Hi list.

I'm quite new to c++ and i have written a program in java that I'd like (or=
 rather need) to translate to c++, but I don't know how to solve this. How=
 do I translate the following dummy java class to an equvalent c++ class? 

public class Test{
    double[][] input;

    public Test(double[][] input){
        this.input =3D input;
    }

    public double[][] getOutput(){
        double[][] output =3D new double[input.length][input[0].length];
        for(int i=3D0; i<output.length; i++)
            for(int j=3D0; j<outout[0].length; j++)
                output[i][j] =3D 2*input[i][j];

        return output;
    }
}

Thanks for your help
