如何释放 BYTE memory？

Question

Quick question: do I have to / how do I release memory from this allocation of memory?

unsigned char *uString = new unsigned char[4096]();

And if I have to, would I do it like this?

free(uString); delete[] uString;

Answer 1

You use the free function when you allocate memory with the C functions like malloc calloc and more.

In c++ you use the operators new and delete (Also thier array friends new[] and delete[] ).

When you want to delete object created with the operator new[] , you call the operator delete[] . For example:

int main(void)
{
    int[] arr = new int[5];
    int* a = new int;
    delete[] arr;
    delete a;
    return 0;
}

And that's all. That will also call the destructor an all of that.
