Multiplication table w/ Array will not work

[ZAMZAMZ]

Anyone know how to add the top layer of my multiplication table?Plus, if the users enters an integer above 10 i get some weird junk value.

#include<iostream>
#include <iomanip>

using namespace std;

int main ()

{
  int size;
  int row;
  int col;
  int nums[row][col];


  cout << "Enter table size" << endl;
  cin >> size;
  cout << endl;

  for(int row = 1; row <= size; row++)
    {
      cout << right << setw(2) << row << setw(2) <<  "|";

      for(int col = 1; col <= size; col++)
        {

        nums[row][col] = row*col;

        cout << setw(4) << nums[row][col];

        }
      cout << endl << endl;
    }

  return 0;
}

This is what it prints when user enter a digit below 10
(This print the numbers out of alignment but in my code they are aligned)

Enter table size
5

1 | 1 2 3 4 5

2 | 2 4 6 8 10

3 | 3 6 9 12 15

4 | 4 8 12 16 20

5 | 5 10 15 20 25


Any digit above ten

Enter table size
11

1 | 1 2 3 4 5 6 7 8 9 10-1081305424

Segmentation fault

I have no idea what you are talking about.

  int row;
  int col;
  int nums[row][col];

¿how big is `nums'? ¿how many elements may it hold?

The top part of the table just like the left side.
1|
2|
3|
etc.
i need a top part like this(but aligned).
1 2 3 4 5 6
----------------
1 |
2 |
3 |
4 |
5 |
6 |

for the 'nums' part, i am not sure. I just thought it was a variable name you need to create for the array. Im new to this :/
