What would make the condition on line 29 change to false, if it is true initially? What in the body of the loop changes the condition?

Same for line 43.

omg im glad you brought that up cause i have no idea how to get the logic right so if they input the wrong thing, it will ask them to try it again.

Unnecessary repetition. Think about this:
1
2
3
4
5
6
7
8
9
10
11
12
 
int input( string text )
{
  int value = 2; // safe default, in case the input fails
  do {
    cout << text << " the array, that is between 2 and 50, inclusive\n";
  } while ( cin >> value && ((value < 2) || (50 < value)) );
  return value;
}


auto row = input( "Enter the number of rows you would like in" );
auto col = input( "Please enter a value for the column of" );
