Is it possible to see the content of a dynamically allocated array, as in:
int *array = new int[dimension];
I only see the value of the pointer.
edit: just found the option "display as an array", but I always have to manually enter the size of the array. Is it possible to get that automagically?
In Eclipse, in order to see the content of a dynamically allocated array (for anyone else who stumbles over this question),
And, dealing with a pointer, take note of clicking Display as Array when hovering on the pointer itself (arrow icon), and not on the value it is referenced at first (say in the position of (x)= counts in the picture).
Otherwise you get an error of the type
Failed to execute MI command:
-data-evaluate-expression [specifics]
Error message from debugger back end:
Cannot access memory at address 0x[address of older*counts]
showing up in the dialogue window just below the list (starting with "Name:" in the screenshot above).
If you want to avoid having to repeatedly do "Display As Array", open the "Expressions" tab and add the expression (*array@dimension). Not sure why the parentheses are necessary. Without them you d get an error.
In the "Expressions" tab, if you do what cleong noted and type (*array@dimension) then you can dynamically set the size of the array to display as well. This even works when you need another expression to get it.
So say you have a variable x that contains your array size, you type (*array@x) and it ll use the content of x as a dimension.
"x" can also be things like struct contents or pointer dereferences and the like - i.e.
(*array@SomePtrToStruct->x)
works just fine.

That s good. I d stick with it. Getting the array automatically is not possible in the general case in C or C++, though surely in some trivial cases it could be done (but probably is not, yet--features need to be implemented before they exist, to paraphrase Raymond Chen).
