Debugging Arrays

[Bazman]

Hi there,

I am debugging a 8*8 array.

When I view it in Auto or Locals and expand it all it shows is what I assume are the rows. the value for each row is simply shows as the memory location of the overall array.

Is there a way for me to view the whole array i.e. by column and row?

And to see the value stored in that location?

also I have a value which I a static int which does not show up in either Auto or Locals how can I view the value of this variable when the program is running?

You'd need to expand the rows too,

Alternately you could use the watch or quick watch windows and type in something like myArray[1][2]

[Bazman]

I cannot expand the rows?

There is a box with a plus in it but nothing happens when I click on it?

[Lindley]

For dynamic-size arrays, you cannot expand an entire row by simply clicking next to it, since the debugger doesn't know how big it is. The syntax then would be,

myArray[1],2
in the watch window.

ah that's it thanks to both of you!!!

can you exaplin to me the syntax though

the myArray[1] is obviously identifying the arrau and the row.

Also can anyone exaplain to me how to view variables of type static int?

It doesn't show up in either auto or locals and doesn;t seem to be doing its job in the program either!

Just type the name of the variable in the watch window. If the var is within scope it should show you the value.

[Bazman]

ahhhh

It come sup with!

step: CXX0017: Error: symbol "step" not found

below is the code, why would this symbol not be found?

void updateMove(int board[][8],int moves[],int choice,int& x,int& y, int& movecounter)
{
	static int step =0;

	step += 10;

	movecounter += 1;
	
	board[x +=  horizontal[moves[choice]]][y +=  vertical[moves[choice]]] = step;
}

[Lindley]

Which line was the debugger stopped on when it said that?

[Bazman]

It is just on the closing brace.

But I have not Pressed F11 to proces it yet.

All other variables within that bloack are still viewable.

[Lindley]

Does it show up if you breakpoint before the closing brace?

[Bazman]

no it has the same error:


step CXX0017: Error: symbol "step" not found


mo matter where you are in the program.

[Lindley]

Make sure optimization is disabled.

[Bazman]

sorry what is optimsiation and how do I disable it?

[Lindley]

Project->Properties->C/C++->Optimization and set the first option to "Disabled". This should be the case by default in the Debug configuration.

[Bazman]

OK I'm usig VC++ 6

In Project settings>C/C++>under optimisations: it has Diable(debug) but this is ghosted out.
