C - Add Item To Array - c

Question

I'm working on a game modification for a third party game (a so called "mod"), and I want to add the player to an array.
I will explain the process of how it works. My code looks like this:
int numElements = 20;
int arrSize = numElements * 2 + 2;
Ped peds[arrSize];
peds[0] = numElements;
int countPeds = GET_PED_NEARBY_PEDS(PLAYER_PED_ID(), peds, -1);
The game function called GET_PED_NEARBY_PEDS will populate the peds array with IDs of the pedestrians walking around the PLAYER_PED_ID (our player).
My goal here is to also add our player to this array aswell. Right now, it only gathers the pedestrians around the player, and I want the player to be included in this array aswell.
I came to the conclusion that I should create a new array, and add the PLAYER_PED_ID to this new array, like so:
Ped newpeds[arrSize + 1];
for (int i = 0; i < arrSize; i++) newpeds[i] = peds[i];
newpeds[arrSize + 1] = PLAYER_PED_ID();
And then instead of using the peds array in my code, I will be using newpeds. But for some reason the modifications don't affect the player, but only the pedestrians around the player (like the first code example).
This is what my full code looks like:
int numElements = 20;
int arrSize = numElements * 2 + 2;
Ped peds[arrSize];
peds[0] = numElements;
int countPeds = GET_PED_NEARBY_PEDS(pedID, peds, -1);
Ped newpeds[arrSize + 1];
for (int i = 0; i < arrSize; i++) newpeds[i] = peds[i];
newpeds[arrSize + 1] = PLAYER_PED_ID();
for (int i = 0; i < countPeds; i++) {
Ped ped = newpeds[i * 2 + 2];
//...
}
How can I add the player to the array? Could it have something to do with the math? Any help is appreciated. :)

Answer 1

This may be because you are trying to add PLAYER_PED_ID() at wrong index.
for (int i = 0; i < arrSize; i++) newpeds[i] = peds[i];
newpeds[arrSize + 1] = PLAYER_PED_ID();
You should be adding PLAYER_PED_ID() at :
newpeds[arrSize] = PLAYER_PED_ID();
