Add entry at the back of `usigned char *`

[queen grove]

The title speaks for itself.

What I have tried:

unsigned char * loop_list = {};

for (int i = 0; i < size; i++)
{
    // add byte to list
    loop_list[i] = buffer[i];
}```
But that just glitches out.

You probably want to use a vector for this

You can’t do this because you cannot just add elements to an array, the size is fixed

If you really have to use pointer arrays for whatever reason, you have to reallocate when the elements surpassed the array size

But check out std::vector which handles it all for you

std::vector

template<
    class T,
    class Allocator = std::allocator<T> >
class vector;
// ... and 1 more

Defined in

<vector>

Oh shoot I just saw the arduino tag

For arduino, I would just recommend stack allocating an array (with a large, fixed size) such as 128 or 512

If you know the max that size could be, you could set this array size to that maximum

unsigned char loop_list[128] = {};

…

For normal devices you might use malloc (for c) or vector, but arduino doesn’t support the c++ stl and malloc can lead to heap fragmentation so better safe than sorry
