Hello,
I'm trying to use two dimensional arrays in NXC, like this:
int onedarray[4];
int twodarray[4][4];
task main()
{
onedarray[2] = 1;
twodarray[2][2] = 1;
}
I read that the stock firmware doesn't support them, so I got John
Hansen's enhanced firmware and put it on my NXT. I downloaded the latest
version of BricxCC, and found and checked the "Enhanced firmware"
checkbox in the preferences. The code still won't compile. I get
line 7: Error: '=' expected
line 7: Error: Identifier expected
line 7: Error: Undefined Identifier 2
line 7: Error: Datatypes are not compatible
line 7: Error: ';' expected
Am I doing something wrong?
How can I use multidimensional arrays?
Thanks,
Trevyn

| (...) The stock firmware supports multi-dimensional arrays but there is a bug in the replace opcode which makes it impossible to replace an element in an array with more than one dimension. In NXC, due to the way the opcodes work in the standard (...) (17 years ago, 31-Mar-08, to lugnet.robotics.nxt)
