The Spaces Between Us. Existentialism vs. Array Display Manipulations

Marth (58)
Get your bodies ready;

this is a seating chart, user chooses how many rows and columns there are, then they are displayed.

Two questions:

1) if you input 10 or more ROWS, you will notice that when it gets to the tenth row, the straight column shifts to the right along with with extra digit in the numbering scheme. i.e. 

1
2
3
4
5
6
7
8
 
...
8  ABCD
9  ABCD
10  ABCD
11  ABCD
12  ABCD

etc..


I want them in a purrrfectly straight line bro. This is an affront to my aesthetic.


SECOND QUESTION:

Along similar lines, I need to institute spaces between the letters (i.e. AB CD or A BCD or ABC D) at user determined interval(s); these are to represent walkways, as a stewardess would traverse on a plane.

I'm sorry to do this to you, but here's the code, if you notice at the bottom, there is a DISPLAY function, wherein I meagerly attempt to right this ship. Heretofore I have failed, much conundrum has befallen I.

a)
if (rows > 10 )

should be:

if (i+1 >= 10 )

b)
for (int j = 0; j < columns; j++) {
if (j == 2) cout << " ";
cout << seating[i][j];
}

c) use std::vector instead of pointers or c-style arrays.
