11 )           What is the output for the following:

for (int x = 1; x <= 7; x++)

cout << “GooDBye\n”;

2 )           What is the output for the following:

for (int x = 1; x <= 7; x++)

cout << “GooDBye”;

3 )           What is the output for the following:

for (int x = 1; x <= 3; x++)

  {for (int y =1; y <= 4; y++)

    cout << (( x+y)*2)<<endl;}

4 ) This is an example of using pointers in code

What is the output for the following:

char x[ ] = {“Have a Nice DAY”};

char *ptr;

ptr = x;                               OR ptr=&x[0];

while (*ptr != ‘\n’)

{  if (*ptr = = ‘a’

      cout << “You Have a Hit\n”;

                    ptr++;}

5 ) This is an example of using pointers in code

What is the output for the following:

int p [ 5 ]= {100,200,300,400,500},*q,x;

q = p[ 4 ];

*q = 250;

p [ 1 ] = *q + 50;

q = p [2 ];

q++;

*q = *(q-1) +50;

q=&p[0];

for (int x = 4; x >= 0; x--)

cout << *(q + x)<<endl;

6 ) This is an example of using pointers in code, HOW WOULD YOU CHANGE THE CODE?               

Change Array notation (use of index) to pointer notation:

a)      int x;

int arrays [ 5 ]= {100,200,300,400,500};

for (int x = 0; x < 5; x++)

cout << arrays [ x ]<< ‘ ‘;

b)  #include <iostream.h>

void swap(float&, float&);   // function receives 2 references

int main()

{  float firstnum = 20.5, secnum = 6.25;

  cout << "The value stored in firstnum is: " << firstnum << endl;

  cout << "The value stored in secnum is: "<< secnum << "\n\n";

  swap(firstnum, secnum);   // call the function with references

  cout << "The value stored in firstnum is now: "

       << firstnum << endl;

  cout << "The value stored in secnum is now: "

       << secnum << endl;

  return 0;}

void swap(float &num1, float &num2)

{  float temp;

  temp = num1;     // save num1's value

  num1 = num2;     // store num2's value in num1

  num2 = temp;     // change num2's value

  return;}

LINKED LIST REVIEW

Using the LINKED LIST do the following:

// This program demonstrates the LINKED LIST member methods/functions

// append; adds a element

// This is a SORTED linked list, insert; puts the element in the location to keep order in    // the sort 

// delete; removes the element stated.
