Question

If i create a heap array inside a loop, do i have to delete it at the end of each loop before i reinitialize it at the beginning of the loop again or will reinitializing the exact same thing again simply overwrite the old array and i can just skip the delete command?

Answer 1

Do you mean something like this?

for (int i = 0; i < 5; i++) {
    char *array = new char[10];
    // ...
    delete[] array;
}

In that case: yes, you do need to delete the array.

If you had written something like this instead,

char *array = 0;
for (int i = 0; i < 5; i++) {
    if (!array) array = new char[10];
    // ...
}
delete[] array;

then no, you can reuse the array across multiple iterations of the loop.
