Memorizzare una matrice di array

[mondobimbi]

se vuoi lavorare in c++ usa la libreria iostream e i manipolatori

#include <iostream>
#include <iomanip>

double **funzione()
{
  double **matr;

  matr = new double*[4];
  for(int i=0; i<4; i++)
    matr[i] = new double[4];

    matr[0][0] = 1.0;
    matr[0][1] = 2.0;
    matr[0][2] = 3.0;
    matr[0][3] = 4.0;

    matr[1][0] = 1.1;
    matr[1][1] = 2.1;
    matr[1][2] = 3.1;
    matr[1][3] = 4.1;

    matr[2][0] = 1.2;
    matr[2][1] = 2.2;
    matr[2][2] = 3.2;
    matr[2][3] = 4.2;

    matr[3][0] = 1.3;
    matr[3][1] = 2.3;
    matr[3][2] = 3.3;
    matr[3][3] = 4.3;

    return matr;
}

int main()
{
  double **p = funzione();

  for(int i=0; i<4; i++) {
    for(int j=0; j<4; j++)
      std::cout << std::setw(10) << std::fixed << p[i][j] ;
    std::cout << std::endl;
  }

  return 0;
}
