Write a C console application that will be used to determine if rectangular packages can fit inside one of a set of spheres. You

MatroZZZ [7]

Answer:

#include <cmath>

#include <iostream>

using namespace std;

int getSphereSize(double length, double breadth, double height) {

double diagonal = sqrt(length * length + breadth * breadth + height * height);

if (diagonal <= 4)

return 4;

if (diagonal <= 6)

return 6;

if (diagonal <= 8)

return 8;

if (diagonal <= 10)

return 10;

if (diagonal <= 12)

return 12;

return 0;

}

int main() {

double length, breadth, height;

int sphereCounts[5] = {0};

int sphereSize;

while (true) {

// Get dimensions of the box

cout << "Enter the dimensions of the box:\n";

cout << "Length: ";

cin >> length;

cout << "Breadth: ";

cin >> breadth;

cout << "Height: ";

cin >> height;

if (length <= 0 || breadth <= 0 || height <= 0)

break;

sphereSize = getSphereSize(length, breadth, height);

if (sphereSize == 0)

cout << "The box cannot fit in any of the spheres";

else

cout << "The box can fit in the " << sphereSize << "-inch sphere";

// Increment the counter

if (sphereSize == 4)

sphereCounts[0]++;

else if (sphereSize == 6)

sphereCounts[1]++;

else if (sphereSize == 8)

sphereCounts[2]++;

else if (sphereSize == 10)

sphereCounts[3]++;

else if (sphereSize == 12)

sphereCounts[4]++;

cout << "\n\n";

}

cout << "\nNumber of 4-inch spheres: " << sphereCounts[0];

cout << "\nNumber of 6-inch spheres: " << sphereCounts[1];

cout << "\nNumber of 8-inch spheres: " << sphereCounts[2];

cout << "\nNumber of 10-inch spheres: " << sphereCounts[3];

cout << "\nNumber of 12-inch spheres: " << sphereCounts[4];

cout << endl;

return 0;

}

Explanation:

The "cmath" library is included in the c++ program. The getSphereSize function is used to return the sphere size the rectangle dimension can fit into. It program continuously prompts the user for the length, breadth, and height of the rectangle and passes the values to the getSphereSize function in the while but breaks if any or all of the variable value is zero.

The sizes of the sphere objects in inches are collected in an array of five integer values of zeros and are incremented by one for every match with a rectangle.

Gwen wants to adjust columns of text that contain money values. Which tab stop option should she choose?

Shtirlitz [24]

Gwen wants to adjust columns of text that contain money values. The tab in excel in the stop option that should she choose is: "The decimal Tab" (Option C)

<h3>

What is the Decimal Tab?</h3>

A Decimal Tab stop is used to align numbers around a decimal point. The decimal point remains in the same location regardless of the amount of digits.

When using this form of tab stop, the numbers must be aligned around a decimal character.

The Beaufort Wind Scale is used to characterize the strength of winds. The scale uses integer values and goes from a force of 0,

joja [24]

Answer:

The equivalent if statements is:

ranforce = randi([0, 12]);

if (ranforce == 0)

disp('There is no wind')

else if(ranforce>0 && ranforce <7)

disp('There is a breeze')

else if(ranforce>6 && ranforce <10)

disp('This is a gale')

else if(ranforce>9 && ranforce <12)

disp('It is a storm')

else if(ranforce==12)

disp('Hello, Hurricane!')

end

Explanation:

<em>The solution is straight forward.</em>

<em>All you need to do is to replace the case statements with corresponding if or else if statements as shown in the answer section</em>
