return 0; } This example demonstrates a basic stack data structure with push , pop , and printStack operations.

~Stack() { delete[] stack; }

public: Stack(int size) { this->size = size; stack = new int[size]; top = -1; }

int main() { Stack stack(5); stack.push(10); stack.push(20); stack.push(30); stack.printStack(); // Output: 10 20 30 cout << "Popped: " << stack.pop() << endl; // Output: Popped: 30 stack.printStack(); // Output: 10 20

class Stack { private: int top; int* stack; int size;
