Question

 int main(void) {
    const char* kung = "Foo";

    delete []kung;
}

In this piece of code, why do I get the following debug assert failed block_type_is_valid ?

Is it because kung pointer is pointing to a constant string in the memory which cannot be de-allocated ?

Answer 1

Because you can’t delete a string literal (which is what kung points to).

You also can’t delete an automatic-storage string (so it’s not really the literal part):

char kung[] = "Foo";
delete []kung;   //still illegal

Only delete[] memory you allocate with new[].
