"in program arrays12.java a swap method is called. does the swap method exchange parameter values x and y?"

1 answer:

6 0

<h2>Yes the swap method exchange parameter values if passed by reference or the value gets changed inside the function.</h2>

Explanation:

Since the program is not given, I will try to guide you about the mode of parameters.

The meaning of swap is interchanging the values. It can be done by using temporary variable or without using it (if the values are integers).

While passing the parameters, there are two ways, call by value/pass by value and call by reference/ pass by reference.

If call by value, then the value gets swapped only inside the function and will not reflected in the calling portion. Call by reference is other way round.

Write only in C, not C++.

yawa3891 [41]

Answer:

#include <iostream>

using namespace std;

int main() {

int k;

double d;

string s;

cin >> k >> d >> s;

cout << s << " " << d << " " << k << "\n" << k << " " << d << " " << s; }

Explanation:

k is int type variable that stores integer values.

d is double type variable that stores real number.

s is string type variable that stores word.

cin statement is used to take input from user. cin takes an integer, a real number and a word from user. The user first enters an integer value, then a real number and then a small word as input.

cout statement is used to display the output on the screen. cout displays the value of k, d and s which entered by user.

First the values of k, d and s are displayed in reverse order. This means the word is displayed first, then the real number and then the integer separated again by EXACTLY one space from each other. " " used to represent a single space.

Then next line \n is used to produce a new line.

So in the next line values of k, d and s are displayed in original order (the integer , the real, and the word), separated again by EXACTLY one space from each other.

The program along with the output is attached.

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.
