Question

I am trying to print out arrays incrementally like this;

TractMultBox->Text = rows[0] + newline;
TractMultBox->Text += rows[1] + rows[0] + newline;
TractMultBox->Text += rows[2] + rows[1] + rows[0] + newline;

which would give an output like this

3
43
543

I can do fine with this code, however. It would like to use a for loop, that would make it easier, since I would like it to output all arrays until max is reached automatically.

Answer 1

Sounds like a job for a for loop indeed perhaps something like this:

#include <iostream>

int main()
{
    int rows[3] = {3, 4, 5};
    for (int i(0); i < 3; ++i)
    {
       for (int j(i); j >= 0; --j)
          std::cout << rows[j];
       std::cout << "\n";
    }
    std::cin.get();
    return 0;
}

If rows contained 345 this would give you the following output:

3
43
543

Not sure if that’s what you wanted but you can adjust the loops accordingly. The key is to have 2 for loops.

Edit: Changed to self contained example you can play with
