1. Implement a class IntArr using dynamic memory. a. data members: capacity: maximum number of elements in the array size: current number of elements in the array array: a pointer to a dynamic array of integers b. constructors: default constructor: capacity and size are 0, array pointer is nullptr user constructor: create a dynamic array of the specified size c. overloaded operators: subscript operator: return an element or exits if illegal index d. "the big three": copy constructor: construct an IntArr object using deep copy assignment overload operator: deep copy from one object to another destructor: destroys an object without creating a memory leak e. grow function: "grow" the array to twice its capacity f. push_back function: add a new integer to the end of the array g. pop_back function: remove the last element in the array h. getSize function: return the current size of the array (not capacity) i.

Poker A poker hand can be stored in a two-dimensional array. The statement int hand[4][13]; declares an array with 52 elements, where the first subscript ranges over the four suits and the second subscript ranges over the thirteen ranks. A poker hand is specified by placing 1's in the elements corresponding to the cards in the hand. See Figure 1. Figure 1 A 2 3 4 5 6 7 8 9 10 J Q K Club 1 Diamond Heart ♥ 1 Spade a 0|0 1 1, 1,
1. Stack Implementation Write a method called insert for the class Stack. The method shall be implemented using an array-based structure. You can assume that String[] stack is defined in the class, which is responsible to store the elements and responsible to enforce the order of first-in last-out, a.k.a., FIFO. Additionally, you can assume there is a pointer called top, that indicates the position of the top of the stack, pointing to the next available position to insert. The method shall: • take a String s as a parameter, and shall add it at the top of the stack. shall return true if the element s was added successfully at the top of the stack, false otherwise. . . The method must check boundaries of capacity and limitation of the Stack. In case the method is invoked to insert an element of the top of the stack that exceeds its current capacity, the method shall handle the situation properly. Do not provide the entire Stack implementation, only the code solution of the method.
