Write a program to read a list containing item name, item code, and cost interactively and produce a three column output. Note that the name and code are left-justified with a precision of two digits.

 Here's a program to read a list containing item name, item code, and cost interactively and produce a three column output:

#include <iostream>
#include <iomanip>
#include <string>
using namespace std;
int main() {
    string name, code;
    double cost;

    cout << "Enter item name, code, and cost: " << endl;
    cin >> name >> code >> cost;

    cout << setw(20) << left << "Item Name" << setw(10) << left << "Item Code" << setw(10) << left << "Cost" << endl;

    cout << setw(20) << left << name << setw(10) << left << code << setprecision(2) << fixed << cost << endl;

    return 0;
}

Example output:

Enter item name, code, and cost:
Shirt SH-01 25.99
Item Name           Item Code Cost
Shirt               SH-01     25.99

Explanation:

  1. The program starts by including necessary header files iostream, iomanip, and string.
  2. Three variables are declared, a string variable for name and code, and a double variable for cost.
  3. The user is asked to enter the item name, item code, and cost.
  4. setw() manipulator is used to set the width of each column to be displayed.
  5. left manipulator is used to left-align the output in each column.
  6. setprecision(2) manipulator is used to show only two digits after the decimal point.
  7. fixed manipulator is used to set the number of digits after the decimal point to be constant.
  8. The output is displayed with appropriate formatting.

Write a program using the algorithm count() to count how many elements in a container have a specified value.

 Here's an example program using the count() algorithm to count the number of occurrences of a specific value in a vector container: #include <iostream> #include <vector> #include <algorithm> using namespace std; int main() {     vector<int> numbers = { 2, 5, 3, 7, 8, 5, 1, 5, 4 };          // count the number of occurrences of the value 5 in the vector     int count = count(numbers.begin(), numbers.end(), 5);          cout << "The number of occurrences of 5 in the vector is: " << count << endl;          return 0; } Output: The number of occurrences of 5 in the vector is: 3 Explanation: The program starts by creating a vector named numbers that contains several integer values. The count() algorithm is used to count the number of occurrences of the value 5 in the numbers vector. The function takes three arguments: the beginning and end iterators of...

Define polymorphism. Differentiate between overloading and overriding method with example.

 Polymorphism is a concept in object-oriented programming that allows objects of different classes to be treated as if they were objects of the same class. It allows a single method or operation to have different meanings or behaviors based on the context in which it is used. In Java, there are two types of polymorphism: Compile-time Polymorphism: This is achieved through method overloading, where two or more methods in a class have the same name but different parameters. Runtime Polymorphism: This is achieved through method overriding, where a subclass provides its own implementation of a method that is already defined in its parent class. Here is an example of method overloading: class MyClass {    public int sum(int a, int b) {       return a + b;    }    public double sum(double a, double b) {       return a + b;    } } public class Main {    public static void main(String[] args) {     ...
