Hello,
I have a simple question which hasn't been answered by the search function of this forum. I'm a newbie, so when explaining, be specific and basic please.
I need to create a dynamic array that can store objects of a class. Then for each object, call functions from class. Once the array ends, i'd like to free the memory.
Thanks!
create an array of pointers to the class. Use new to create the class, the -> operator to call members, and delete to free the memory. Maybe it would be easier to create a function to erase the array, so that it iterates through each element and calls delete.
Try this:
Code:MyClass *array[2];
array[1] = new MyClass;
array[2] = new MyClass;
array[1]->MyFunc();
delete [] array;
array = NULL;
:confused: it has to be dynamic.
I don't even know what Indigo said.
You have to make a dynamic array. The best option in C++ is a container like vector. IMO, C++ newbies should learn vectors before dynamic C style arrays. If you cannot use vector or choose not to, then you must use new to allocate space for your array so that you can have a dynamic size. The downside of using new is that you have to remember to call delete[] on the array when the function ends, no matter how it ends or you leak the memory. The vector class takes care of that for you.
>> create an array of pointers to the class
I don't see why you need to create an array of pointers, an array of objects should be fine.

That code is not even correct, besides the fact that it doesn't solve the OP's problem.
>array[2] = new MyClass;
Beautiful example of undefined behaviour.
Well thanks; I used the NEW command.
I was hoping you could provide the code, but after a while of messing around I got the solution with your guidance everyone.
PC *obj = new PC [size];
