Hollow Right Triangle - 2

Given an integer number

N as input. Write a program to print the hollow right-angled triangular pattern of N lines as shown below.Note: There is a space after each asterisk (*) character.Input

The first line of input is an integer

Type two statements that use rand() to print 2 random integers between (and including) 100 and 149. End with a newline. Ex:

101

133

Note: For this activity, using one statement may yield different output (due to the compiler calling rand() in a different order). Use two statements for this activity. Also, srand() has already been called; do not call srand() again.

#include <cstdlib> // Enables use of rand()

#include <ctime>  // Enables use of time()

using namespace std;

int main() {

  int seedVal;

  cin >> seedVal;

  srand(seedVal);

  /* Your solution goes here */

  return 0;

}

Using the code stub below, type a statement using srand() to seed random number generation using variable seedVal. Then type two statements using rand() to print two random integers between (and including) 0 and 9. End with a newline. Ex:

 5

 7

Note: For this activity, using one statement may yield different output (due to the compiler calling rand() in a different order). Use two statements for this activity. Also, after calling srand() once, do not call srand() again.

#include <iostream>

#include <cstdlib> // Enables use of rand()

using namespace std;

int main() {

  int seedVal;

  cin >> seedVal;

  /* Your solution goes here */

  return 0;

}

Using the code stub below, write a program that reads a person's first and last names, separated by a space. Then the program outputs last name, comma, first name. End with newline.

Example output if the input is: Akua Mperey

Mperey, Akua

#include <iostream>

#include <string>

using namespace std;

int main() {

  string firstName;

  string lastName;

  /* Your solution goes here */

  return 0;

}

Using the code stub below, output all combinations of character variables a, b, and c, in the order shown below. If a = 'x', b = 'y', and c = 'z', then the output is:

xyz xzy yxz yzx zxy zyx

Your code will be tested in three different programs, with a, b, c assigned with 'x', 'y', 'z', then with '#', '$', '%', then with '1', '2', '3’.

#include <iostream>

using namespace std;

int main() {

  char a;

  char b;

  char c;

  cin >> a;

  cin >> b;

  cin >> c;

  /* Your solution goes here */

  cout << endl;

  return 0;

}

Print a message telling a user to press the letterToQuit key numPresses times to quit. End with newline.

•Ex: If letterToQuit = 'q' and numPresses = 2, print:

#include <iostream>

using namespace std;

int main() {

  char letterToQuit;

  int numPresses;

  cin >> letterToQuit;

  cin >> numPresses;

  /* Your solution goes here */

  return 0;

}

Create a class called myMath. This class only contains one basic data type (float x). Your class should mimic the +,-,*,/ function in a basic data type. In other words, you need to provide the basic math operations for the objects created under myMath.

main()

{

  myMath m1(10),m2(2),m3; //you can change 10 and 2 to any value to test your code.

m3 = m1 + m2;

  cout <<"\nAddition: "<< m3.getX(); //output is 12

  m3 = m1 - m2;

  cout <<"\nSubtraction: "<< m3.getX(); //output is 8

  m3 = m1 * m2;

  cout <<"\nMultiplication: "<< m3.getX(); //output is 20

  m3 = m1 / m2;

  cout <<"\nDivision: "<< m3.getX(); //output is 5

}
