please help me with these functions from c++

1. Given two int parameters, oldValue and newValue, replace the first occurrence of the oldValue with the newValue.
2. Given two int parameters, oldValue and newValue, replace all occurrences of the oldValue with the newValue.
3. Traverse the calling object and search for the value passed by the parameter; return true if found and false if not found. Make sure you stop the loop if the value is found; no need to keep on iterating.

class Node { public: Node() : data(0), next(nullptr) {} Node(int theData, Node *newNext) : data(theData), next(newNext){} Node* getNext() const { return next; } int getData( ) const { return data; } void setData(int theData) { data = theData; } void setNext(Node *newNext) { next = newNext; } ~Node(){} private: int data; Node *next; // Pointer that points to next node. };

class AnyList { public: AnyList() : first(nullptr), count(0) {}

void print() const;

void clearList(); ~AnyList();

private: Node *first; // Pointer to point to the first node in the list. int count; // Variable to keep track of number of nodes in the list. };

#endif

thank you
