[C++] Iterating Over Arrays

[wtd]

When iterating over arrays in C++, it's tempting to use something along the lines of:

code:

int length_of_array = 10; int my_array[length_of_array]; // now, let's populate the array with values for (int i = 0; i < length_of_array; i++)    my_array[i] = i * 2;

There's nothing technically incorrect with this, but there's another method which fits better with standard practice as seen in the Standard Template Library.

code:

int length_of_array = 10; int my_array[length_of_array]; int * beginning of_array = my_array; int * end_of_array = my_array + 10; // now, let's populate the array with values for (int * iterator = beginning of_array; iterator != end_of_array; iterator++)    *iterator = iterator - my_array;
