Push the numbers back into the array as you find them. Then iterate through the array to print or change it as needed. I generally use vectors and the syntax for that is:
vector_name.push_back(value_name)
I'm not sure if arrays use the same syntax as vectors, but you could try, if not try using a vector.
Syntax: vector<int>vector_name{};
Or look through StackOverflow as I guarenttee you this question has probably been answered there.

arrays are immutable, you would need to use a vector or set the array to a fixed size beforehand arr[100] for example.
alternatively keep allocating more memory and deleting the previous array.

arrays can't have numbers pushed into mr.robot

Yeah i use vectors, not much knowledge on arrays in the c lang. Thanks for clearing that up, destro. I would use a vector then

no problem! usually I keep to this philosophy :
known number of elements? array
possibly more or less than needed? vector
