Define a class Complex to represent complex numbers. All complex numbers are of the form x + yi, where x and y are real numbers, real numbers being all those numbers which are positive, negative, or zero.

Answer:

The program in C++ is as follows:

#include<bits/stdc++.h>

using namespace std;

class Complex {

public:

 int rl, im;

Complex(){ }

Complex(int Real, int Imaginary){

 rl = Real;  im = Imaginary;

}

};

int main(){

   int real, imag;

   cout<<"Real: ";    cin>>real;

   cout<<"Imaginary: ";    cin>>imag;

Complex ComplexNum(real, imag);

cout<<"Result : "<< ComplexNum.rl<<" + "<<ComplexNum.im<<"i"<<endl;

}

The new software organization requires a new point of sale and stock control system for their many stores throughout Pakistan to replace their aging mini-based systems.
A sales assistant will be able to process an order by entering product numbers and required quantities into the system. The system will display a description, price, and available stock. In-stock products will normally be collected immediately by the customer from the store but may be selected for delivery to the customer's home address for which there will be a charge. If stock is not available, the sales assistant will be able to create a backorder for the product from a regional warehouse. The products will then either be delivered directly from the regional warehouse to the customer's home address, or the store for collection by the customer. The system will allow products to be paid for by cash or credit card. Credit card transactions will be validated via an online card transaction system. The system will produce a receipt. Order details for in-stock products will be printed in the warehouse including the bin reference, quantity, product number, and description. These will be collected by the sales assistant and given to the customer. The sales assistant will be able to make refunds, provided a valid receipt is produced. The sales assistant will also be able to check stock and pricing without creating an order and progress orders that have been created for delivery.

The program you wrote in Stacks 1 is incomplete. Without a destructor it creates a memory leak. A destructor has been defined in this program but it is incorrect. To visualize how the destructor works, a cout statement has been added. Fix the errors, including the cout statement, to display the value in each node of the stack before releasing the memory.
Write a loop in main() to enter an unknown number of positive integers. The loop stops when you enter 0 or a negative number. As you are entering integers, they are to be pushed onto a stack.
Ex.: If the user enters '10 20 30 -1` the output (from the destructor) should be:
30 - deleted!
20 - deleted!
10 - deleted!
Empty stack!
Ex.: If the user enters '-1` the output should be:
Empty stack!
This is the code:
#include
using namespace std;
class Stack_int
{
private:
// Structure for the stack nodes
struct StackNode {
int value; // Value in the node
StackNode *next; // Pointer to next node
};
StackNode *top; // Pointer to the stack top
int length; // Number of nodes
public:
Stack_int(){ top = NULL; length = 0; } //Constructor
~Stack_int(); // Destructor
// Stack operations
// bool isEmpty();
bool push(int);
// int pop();
// int peek();
// int getLength();
};
/**~*~*
Member function push: pushes the argument onto the stack.
*~**/
bool Stack_int::push(int item)
{
StackNode *newNode; // Pointer to a new node
// Allocate a new node and store num there.
newNode = new StackNode;
if (!newNode)
return false;
newNode->value = item;
// Update links and counter
newNode->next = top;
top = newNode;
length++;
return true;
}
/**~*~*
Destructor
*~**/
Stack_int::~Stack_int()
{
StackNode *currNode;
// Position nodePtr at the top of the stack.
currNode = top;
// Traverse the list deleting each node.
while (currNode)
{
cout << currNode->value << " - deleted!" << endl;
delete currNode;
currNode = NULL;
currNode = currNode->next;
}
cout << "Empty stack!" << endl;
}
int main() {
Stack_int s;
int item;
return 0;
}

You are responsible for a rail convoy of goods consisting of several boxcars. You start the train and after a few minutes you realize that some boxcars are overloaded and weigh too heavily on the rails while others are dangerously light. So you decide to stop the train and spread the weight more evenly so that all the boxcars have exactly the same weight (without changing the total weight). For that you write a program which helps you in the distribution of the weight.
Your program should first read the number of cars to be weighed (integer) followed by the weights of the cars (doubles). Then your program should calculate and display how much weight to add or subtract from each car such that every car has the same weight. The total weight of all of the cars should not change. These additions and subtractions of weights should be displayed with one decimal place. You may assume that there are no more than 50 boxcars.
Example 1
In this example, there are 5 boxcars with different weights summing to 110.0. The ouput shows that we are modifying all the boxcars so that they each carry a weight of 22.0 (which makes a total of 110.0 for the entire train). So we remove 18.0 for the first boxcar, we add 10.0 for the second, we add 2.0 for the third, etc.

One of your suppliers has recently been in the news. Workers complain of long hours, hot and stuffy workrooms, poor lighting, and even no functioning bathrooms. Some workers are less than 14 years old. Workers are paid 10 cents for each piece they complete, and fast workers are capable of finishing 50 pieces. What is the best way to describe these working conditions?

Write a function that takes number between 1 and 7 as a parameter and prints out the corresponding number as a string. For example, if the parameter is 1, your function should print out one. If the parameter is 2, your function should print out two, etc. If the parameter is not between 1 and 7, the function should print an appropriate error message. In your file, you should include a main() that allows the user to enter a number and calls your function to demonstrate that it works.

The divBySum method is intended to return the sum ofall the elements in the int arrayparameter arr that are divisible by the intparameter num. Consider the following examples, in whichthe array arrcontains {4, 1, 3, 6, 2, 9}.The call divBySum(arr, 3) will return 18,which is the sum of 3, 6, and 9,since those are the only integers in arr that aredivisible by 3.The call divBySum(arr, 5) will return 0,since none of the integers in arr are divisibleby 5.Complete the divBySum method using anenhanced for loop. Assume that arr isproperly declared and initialized. The method must use anenhanced for loop to earn full credit./** Returns the sum of all integers inarr that are divisible by num* Precondition: num > 0*/public static int divBySum(int[] arr, int num)
