Thread: dynamic memory allocation

this is the question; Write a function that builds a two-dimensional multiplication table with arbitrary sizes for the
two dimensions.

This is what I have done. I have allowed the user to input whatever size table they want by arbitrarily choosing what value they can input. However I cannot get the board to have blank squares. I thought the char would do it. Any suggestions? thanks

Code:

#include <iostream>


using namespace std;


char SQAURE_CHAR = {' '};


const int Board_Size = 14;


int main()
{


    int **p_p_multtable;


    p_p_multtable = new int* [Board_Size];


    for (int i = 0; i < Board_Size; i++)
    {
        p_p_multtable[i] = new int [Board_Size];
    }


    for (int i = 0; i < Board_Size; i++)
    {
        for (int j = 0; j < Board_Size; j++)
        {
          p_p_multtable[i][j] = SQAURE_CHAR;
        }
    }


    for (int i = 0; i < Board_Size; i++)
    {
        delete [] p_p_multtable[i];
    }


    for (int i = 0; i < Board_Size; i++)
    {
        for (int j = 0; j < Board_Size; j++)
        {
          cout << p_p_multtable[i][j];
          if (j!= Board_Size - 1)
          {
              cout << " | ";
          }
        }
        cout << endl;
        if (i != Board_Size - 1)
        {
            cout << "----------------------------" << endl;
        }
    }
    return 0;
}

sorry noticed some mistakes changed the int to char but still not getting a blank board. below is rectified code.

Code:

#include <iostream>


using namespace std;


char SQAURE_CHAR = {' '};


const int Board_Size = 14;


int main()
{


    char **p_p_multtable;


    p_p_multtable = new char* [Board_Size];


    for (char i = 0; i < Board_Size; i++)
    {
        p_p_multtable[i] = new char [Board_Size];
    }


    for (char i = 0; i < Board_Size; i++)
    {
        for (char j = 0; j < Board_Size; j++)
        {
          p_p_multtable[i][j] = SQAURE_CHAR;
        }
    }


    for (char i = 0; i < Board_Size; i++)
    {
        delete [] p_p_multtable[i];
    }


    for (char i = 0; i < Board_Size; i++)
    {
        for (char j = 0; j < Board_Size; j++)
        {
          cout << p_p_multtable[i][j];
          if (j!= Board_Size - 1)
          {
              cout << " | ";
          }
        }
        cout << endl;
        if (i != Board_Size - 1)
        {
            cout << "----------------------------" << endl;
        }
    }
    return 0;
}

Why are you (partially) deleting the array before you print it???
