This is all apart of one code, please help solve in C++

Multiple integers, representing the number of ducklings, are read from input and inserted into a linked list of DuckNodes. Find the sum of all the integers in the linked list of DuckNodes. Ex: If the input is 116 , then the output is: 17 int main() DuckNode* headDuck = nullptr; DuckNode* currDuck = nullptr; DuckNode* lastDuck = nullptr; int count; int inputValue; int i; int sum; cin >> count; headDuck = new DuckNode (count); lastDuck = headDuck; for (i =; i >> inputValue
