Question

Draw the pictures representing each of the declarations below.  

These problems build on each other, so in some cases a picture refers to something previously created.

/* Lab 13: Picture Dynamic Memory

Objective: Draw Pictures of Computer Memory

#include<iostream>

using namespace std;

int main() {

// A.

int numbers[5];

//-------------

// B.   

char words[3][10];

//----------------

// C.

int *pNumbers = new int[4];  

//-------------------------

// D.

char **pWords;

pWords = new char*[3];

for( int i=0; i<3; i++) {

pWords[i] = new char[5];

}

//---------------------------

// E.

//Assume we have:

class Student{

public:

Student(){

initials[0] = 'D';

initials[1] = 'F';

initials[2] = 'R';

UIN = 12345;

}

private:

char initials[3]; // Delano Franklin Roosevelt would be DFR

long UIN;

};

// Now draw the following:

Student cs141[3];

Student *pStudent = &cs141[2];

Student *pOther = pStudent;

//--------------------------------------

//F.

//Assume we have:

struct Node {

int data;

Node *pNext;

};

// Now draw the following:

Node n1;

n1.data = 3;

Node *pNode = new Node;

pNode->data = 5;

pNode->pNext = &n1;

pNode->pNext->pNext = pNode;

///======================================

return 0;

}
