c++ - Delete array from an offset -

-

lets allocate array of ints

int test[] = new int[100];

i take pointer somewhere in middle

int *temp = &test[50];

then call delete[] on temp

delete[] temp

how compiler know size of elements delete in case?

it won't (or will, don't know). you're invoking undefined behavior. you're allowed call delete[] on pointer allocated new[].

for example, crash in msvs.
