Given an int variable n that has been initialized to a positive value and, in addition, int variables k and total that have alre

Fudgin [204]

Answer:

The c++ program to implement the while loop is given below.

#include <iostream>

using namespace std;

int main() {

// declaration of integer variables

int k, n, total;

// initialization of integer variables

k=1, n=4, total=0;

// loop executed till value of k becomes equal to value of n

while( k <= n ){

// cube of every integer is added to the variable total

total = total + ( k * k * k );

// value of k is incremented to go to the next number

k = k + 1 ;

}

return 0;

}

Explanation:

The program begins with the declaration of integer variables.

int k, n, total;

This is followed by initialization of these variables.

k=1, n=4, total=0;

The while loop runs over the variable k which is initialized to 1. The loop runs till value of k reaches the value of integer n.

First, cube of k is computed and added to the variable total.

After first execution of the loop, total is initialized to the cube of 1.

Next, value of variable k is incremented by 1 so that k is initialized to next integer.

After first execution of the loop, k is incremented from 1 to 2.

while( k <= n )

{

total = total + ( k * k * k );

k = k + 1 ;

}

When the value of k reaches the value of integer n, the cube of n is calculated and added to the variable, total.

When k is incremented, it becomes more than n and hence, loop gets terminated.

As the return type of main is int, the program terminates with the statement shown below.

return 0;

No output is displayed as it is not mentioned in the question.

No user input is taken as it is mentioned that integer variables are already initialized.

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.

Can you help me in this question

Amiraneli [1.4K]

Answer:

6 2 and 0

Explanation:

This algorithm doesn't work if the list is not ordered ascending.

In this example it is not, and indeed the item "1" is never found.

first cycle: first=0, last=12 so midpoint=6

second cycle: first=0, last=5 so midpoint=2

last cycle: first=0, last=1 so midpoint=0

then last is assigned -1 so the while statement is no longer true.

"Write code that prints: Ready! countNum ... 2 1 Start! Your code should contain a for loop. Print a newline after each number a

BartSMP [9]

Explanation:

#include <iostream.h>

#inlcude<conion.h>

void main()

{

int count, x;

clrscr();

cout<<"Enter the count:";

cin>> count;

cout<<"Ready!\n";

for(x=count;x>0;x--)

{

cout<<x<<"\n";

}

cout<<"Start";

getche();

}

This is a simple program where the output is expected to be in reverse order. So we run a for loop starting from the count and decrements the counter by 1 every time when the loop runs and print the value. So to print the output in "new line" we include "\n".

Which sql keyword is used to retrieve a minimum value from an attribute in a table

konstantin123 [22]

The SQL keyword that is often used to retrieve a minimum value from an attribute in a table is the MIN function.
