What are the benefits of passing by pointer over passing by reference in C++?
Lately, I have seen a number of examples that chose passing function arguments by pointers instead of passing by reference. Are there benefits to doing this?
The question is the following: consider this piece of code:
void aTest(int a, int b)
printf("%d + %d = %d", a, b, a + b);
void function1(void (*function)(int, int))
I'm a bit confused as to how I would pass a pointer to a pointer function. I have a function that takes a pointer to a function which I understand without problem (ExecBlock). But I'm given another prototype of a function (ExecBlock2) which takes the dere...
