Write a program that illustrates the application of multiple catch statements.

 Here's an example program that uses multiple catch statements to handle different types of exceptions:

#include <iostream>
#include <string>
using namespace std;

int main() {
    try {
        int num1, num2, result;

        cout << "Enter two numbers to divide: ";
        cin >> num1 >> num2;

        if (num2 == 0) {
            throw string("Cannot divide by zero!");
        }
        result = num1 / num2;
        cout << "Result: " << result << endl;
    } catch (string errorMessage) {
        cout << "Error: " << errorMessage << endl;
    } catch (...) {
        cout << "Unknown error occurred." << endl;
    }
    return 0;
}

In this program, we ask the user to enter two numbers and attempt to divide them. If the second number is zero, we throw a string exception with an appropriate error message. We then use two catch statements to handle exceptions: the first catches any string exception and prints the error message, while the second catches any other type of exception (or even no exception at all) and prints a generic error message.

Here's an example output of the program:

Enter two numbers to divide: 10 0
Error: Cannot divide by zero!

And another example output where the division is successful:

Enter two numbers to divide: 12 4
Result: 3

As you can see, when an exception is thrown, the program jumps immediately to the catch block that can handle it. If no catch block can handle the exception (such as in the case of an unexpected type of exception), the program will terminate and print an error message.

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) {     ...
