Write a program checkerboard3x3.cpp that asks the user to input width and height and prints a checkerboard of 3-by-3 squares. (It should work even if the input dimensions are not a multiple of three.) . Don't use function.

Example 1:

Input width: 16
Input height: 11

Shape:
***   ***   ***

Expert Solution

C++ Program

#include <iostream>
using namespace std;

int main() {

int width,height; // Declare two integer variables width and height
// input two integer variables
cout<<"Input width: "; cin>>width;
cout<<"Input height: "; cin>>height;

string board = ""; // declare string obj board initialize ""

cout<<"\n\nShape:"<<endl;

for (int i = 0; i < height; ++i) // create for loop i until height outer loop
   {
for (int j = 0, c = '*'; j < width; ++j, c = '*') // create for loop j and declare initeger c='*' until width
       {
           // check condition with bitwise operator 'and' and 'xor' values if it true c=' '(space)
           // calculate every 3 rows display gap
if (((j / 3) & 1) ^ ((i / 3) & 1))
c = ' ';

board += (char)c; // else, convert c integer into character and add character '*' into board object
}

board += '\n'; // the control is passed into new line
}

cout <<board; // print the entire string outside for loops
return 0;
}

OUTPUT-1

Input width: 16

Write a program that asks the user for an integer. The program checks and prints to the screen whether the number is prime or not. For example, if user enters 17, the program should print “17 is prime”; if the user enters 20, the program should print “20 is not prime”. please do it with a “ while Loop”, Thanks..

Must implement a simple program that asks the user for a width and a height, storing them as double values. Afterwards, you compute area and perimeter as if the shape were a rectangle. Output the results. Then, you compute the area and perimeter as if the shape were a right triangle and you have been given the base and height. Area and Perimeter Calculator Enter width: 3 Enter height: 5 If your shape is a rectangle, its area is 15.0...

Write Java program that asks a user to input a letter, converts the user input to uppercase if the user types the letter in lowercase, and based on the letter the user the user enters, display a message showing the number that matches the letter entered. For letters A or B or C display 2 For letter D or E or F display 3 For letter G or H or I display 4 For letter J or K or L...

a). Write a program that asks the user to enter an integer N and prints two integers, root and power, such that 1 < power < 6 and N = root ** power. If no such pair of integers exists, it should print a message to that effect. There are two loops, one for power and one for root. Order the loops so that if N = 64, then your program find that N = 8 ** 2 rather than...

Write a Java program that prompts the user to input a string and prints whether it is a palindrome. A palindrome is a string which reads the same backward as forward, such as Madam (disregarding punctuation and the distinction between uppercase and lowercase letters). The program must use the stack data structure. The program must include the following classes: The StackX class (or you can use the Java Stack class). The Palindrome class which must contain a method named palindrome()...

Write a program, ArrayRange, that asks the user to input integers and that displays the difference between the largest and the smallest. You should ask the user the number of integers s/he would like to enter (this will allow you to set the length of the array). Allow the user to input all the numbers and then store them in the array. Search the array for the largest number, then search for the smallest, and finally compute the calculation. Display...

Write a program that asks the user to input a set of floating-point values. When the user enters a value that is not a number, give the user a second chance to enter the value. After two chances, quit reading input. Add all correctly specified values and print the sum when the user is done entering data.
