That worked! Thanks psyking!

So I guess my question would be then; how do I sum up the different columns/rows/diagonals? I know it has to be the one for loop with sum=sum+grid[][], that much is correct, but I don't understand how to create variability in the summation.

Do I need to do something like this for each function...

grid[i][j] for one of the loops
grid[j][i] for another
grid[i][i] for another
grid[j][j] for another?

am I on the right track?

The program looks like this

[program]
Unsorted data:
003BF8C8

Sorted data:
003BF8C8
[/program]


when the data in the in.txt file is as follows:

[data]
122 45 345 35 65 45 678 54 34 72
345 87 234 878 7 456 234 32 1 46
34 567 3 199 61 318 415 2 678 43
4 657 46 66 687 54 435 65 59 219
62 76 543 5 47 89 37 65 47 68
52 234 619 54 52 34 467 67 9 65
56 119 67 554 6 18 68 40 56 47
32 547 26 71 194 34 42 8 98 90
26 16 7 37 356 73 26 45 62 236
61 36 43 45 87 49 237 532 17 38
[/data]

and I'm trying to sort it from least to greatest. it does save the random string of numbers, so atleast I know the print_data function works. I just need to know how to put the in.txt file into the array A[]

I forgot to mention that the random string of numbers/letters I get for an output is always different and random. I don't really understand it. I'm relatively new to C++.
