Sometimes when English isn't your native language it is even more difficult to explain what you want to do than it is for us native English speakers. To use multidiminsional arrays you can do something like this:

int array[2][2];

which declares a variable on the stack with enough memory for 4 ints. Now to get the information into that array you can do several things. Here's one way:

 Help with Code Tags 
 C++ Syntax (Toggle Plain Text) 
for(int i = 0; i < 2; ++i)
{
  for(int j = 0; j < 2; ++i)
 {
     cout <<"enter a value" << endl;
     cin >> array[i][j];
  }
}
 
and to dispay the values you use another nested loop except the body would be something like:
 
//pseudocode to display array as a table
for()
  for()
     cout << array[i][j] << ' ';  
  cout << endl;
for(int i = 0; i < 2; ++i)
{
  for(int j = 0; j < 2; ++i)
 {
     cout <<"enter a value" << endl;
     cin >> array[i][j];
  }
}

and to dispay the values you use another nested loop except the body would be something like:

//pseudocode to display array as a table
for()
  for()
     cout << array[i][j] << ' ';  
  cout << endl;
