How can I change the size of an array in C?

Question

I am experimenting a little bit with gamestudio. I am making now a shooter game. I have an array with the pointer\'s to the enemies. I want. to when an enemy is killed. remo

Answer 1

I wanted to lower the array size, but didn't worked like:

myArray = new int[10];//Or so.

So I've tried creating a new one, with the size based on a saved count.

int count = 0;

for (int i = 0; i < sizeof(array1)/sizeof(array1[0]); i++){
  if (array1[i] > 0) count++;
}

int positives[count];

And then re-pass the elements in the first array to add them in the new one.

//Create the new array element reference.

int x = 0;

for (int i = 0; i < sizeof(array1)/sizeof(array1[0]); i++){
  if (array1[i] > 0){ positives[x] = array1[i]; x++; }
}

And here we have a brand new array with the exact number of elements that we want (in my case).
