Using "new" in C++ vs array[123] or *array = malloc(123)

Sorry if this is an easy question, but I don't know anything about C++ and have been dabbling with some libraries written in C++.

Is there any difference between these statements?

Code:

---

uint8_t mybuffer[100]; //C

uint8_t *mybuffer = new uint8_t[100]; //C++

---

Yes... one works in C the other does not.

And of course the type of mybuffer would be different in each case; the second one will necessarily use extra storage (since you'll have the storage for the pointer plus the 100 uint8_t elements); it is your responsibility to clean up the memory in the second case with delete[], while the system will take care of the first one for you.

Yes there is. Use the first one when possible.
