What is the output

  

1 ) What is the output for the following:

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

cout << “GooDByen”;

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)<

}

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 Hitn”;

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)<

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 ]<< ‘ ‘;

#include

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 << "nn";

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;

}

STACK QUEUE REVIEW

Use the Stack and Queue class declaration/implementation as in Programs 15.1 and 15.3 of Bronson or your text. Show what is written/output by the following segments of code.

Recursion Review

cin>> : is input from the key board. 

Problem1: Look at the following program, the input will be 19, 23, 55, 88, m one at a time.

Output:

What is the output?

What is the Base Case?

What is the recursive Case?

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.
