**Loyalty Program Management for Customer Purchases: A Coding Challenge**This exercise involves revising a program to monitor loyalty points for three customers: A, B, and C. Below are the specifications and an example code snippet to guide you in achieving the program's objectives.**Program Specifications:**1. **Input Process:** - When a customer makes a purchase, the program reads two inputs: - A string, either "A", "B", or "C", that identifies the customer. - A float representing the amount spent in dollars.2. **Program Termination:** - The program ends when the input reads "nobody", signaling no further purchases.3. **Loyalty Program Requirements:** - Customers earn one loyalty point for purchases totaling $10.00 or more. - If a customer accumulates six loyalty points, their total resets to one point. - Points are earned and tracked individually, without influence from other customers' purchases.4. **Code Snippet Overview:**```cpp#include using namespace std;int points = 0;void updateLoyaltyCard() { points++;}int main() { int customerAPoints = 0; int customerBPoints = 0; int customerCPoints = 0; string customer; float purchase; bool looping = true; while (looping) { cout << "Customer: "; cin >> customer; if (customer == "nobody") { break; } // Additional code logic will be needed here to manage purchases and points. } return 0;}```**Instructions for Code Modification:**- You can customize the program to effectively fulfill the loyalty program goals mentioned above. This will involve adding logic to calculate and update each customer's points based on the specified conditions.**Explanation of Code Structure:**- The program uses a `while` loop to continually prompt for customer actions until "nobody" is entered.- Variables for each customer (`customerAPoints`, `customerBPoints`, `customerCPoints`) keep track of individual loyalty points.- Modify the `updateLoyaltyCard()` function and main logic to implement the point earning system and reset condition effectively.By following the outlined requirements and modifying the code snippet, you will create an effective loyalty program management system for the given customers. ### Generating Random Numbers in C++#### IntroductionThis tutorial demonstrates how to write a C++ program that generates 20 random numbers between 10 and 99, inclusive.

### Generating Random Numbers in C++

#### Introduction
This tutorial demonstrates how to write a C++ program that generates 20 random numbers between 10 and 99, inclusive. A seed value is read from standard input to initiate the random number generation sequence.

#### Code Explanation

```cpp
#include <iostream>
#include <stdlib.h>
using namespace std;

int main() {
int seed;
cout << "Seed: ";
cin >> seed;
cout << endl;

srand(seed);

return 0;
}
```

#### Detailed Breakdown

- **Header Files**:
- `#include <iostream>`: This allows for input and output operations.
- `#include <stdlib.h>`: Includes functions for performing general functions such as memory allocation, process control, conversions, and more. Specifically, it provides the `srand` function for seeding the random number generator.

- **Namespace**:
- `using namespace std;`: This line allows the use of standard C++ library objects and functions without prefixing them with `std::`.

- **Main Function**:
- `int main() { ... }`: Defines the entry point of the program.

- **Seed Input**:
- `int seed;`: Declares an integer variable, `seed`, to store the user's input.
- `cout << "Seed: ";`: Prompts the user to enter a seed value.
- `cin >> seed;`: Reads the seed value from standard input.
- `cout << endl;`: Outputs a newline character for formatting.

- **Random Number Initialization**:
- `srand(seed);`: Seeds the pseudo-random number generator used by `rand()` with the user-provided seed value, ensuring different sequences of random numbers.

- **Program Exit**:
- `return 0;`: Indicates that the program executed successfully.

This program demonstrates how to set up the random number generator, though does not yet include the logic to generate and print the random numbers themselves. Further logic is required to complete the task, typically involving loops and the `rand()` function to generate and print the numbers.

Using python, please explain 1: A positive integer greater than 1 is said to be prime if it has no divisors other than 1 and itself. A positive integer greater than 1 is composite if it is not prime. Write a program that asks the user to enter an integer greater than 1, then displays all of the prime numbers that are less than or equal to the number entered The program should work as follows: Once the user has entered a number, the program should populate a list with all of the integers from 2 up through the value entered. The program should then use a loop to step through the list. The loop should pass each element to a function that displays the element whether it is a prime number.
I could really use some help with a problem I got for coding. A screenshot showing an example would help.
In python This assignment assess problem solving ability and the use of the modulo operator, functions, lists and nested loops. The Modulo (%) operator returns a remainder of the two numbers divided. e.g. 9 % 2 will yield a 1 because 9/2 = 4 and the remainder is 1. Write one program that will compute both the Least Common Multiple, and the Greatest Common Factor of two random numbers between 2 and 30. The program will display all factors and multiples of the two numbers. When displaying the multiples of the numbers, only display up to the first input times the second input. Use functions to compute the answers. Loop the program so that the user try again. create the loop so that hitting enter will continue. The example is below: Integer1: 12Integer2: 3 The Multiples of 3 are 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, The Multiples of 12 are 12, 24, 36, The lowest common Multiples is 12 The Factors of 3 are 1, 3, The Factors of 12 are 1, 2, 3, 4, 6, 12, The greatest…
In python, write a code that allows the user to input two non-negative number sequences in increasing order (the numbers entered are always getting bigger, and no number repeats), both terminated by a -1. The size of each sequence can vary (maybe sequence - 1 has four numbers, and sequence - 2 has seven). The output of this code should be a third sequence that is a combination of both sequences 1 and 2 and is sorted in non-decreasing order. Note: Non-decreasing order means there can be a repeated number in the third sequence (see example 1). A strictly increasing order sequence cannot have repeat numbers at all (see example 3). Remember, all input sequences must be in strictly increasing order! please do this using python, only using while loops. NO language of "break" or "len" please. Hint: we can use three separate lists to solve this code.
In Java Write a program that prints the 128-character ASCII table. It should print the tablein eight tab-separated columns. The first column contains a "Dec" heading (fordecimal number) with the numbers 0 through 31 below it. The second columncontains the ASCII characters associated with the numbers 0 through 31. The nextcolumns contain the subsequent numbers and associated ASCII characters. See thebelow sample output for details. Be aware that that output was produced by aprogram running in a console window in a Windows environment. If you runyour program in a different environment, the first 32 characters and the lastcharacter will probably be different from what’s shown below.Note that some characters display in a non-standard manner. For example, thenumber 7 corresponds to a bell sound. You can’t see a sound, but you can see thevacant spot for 7’s character in the below table. The number 8 corresponds to thebackspace character. You can’t see a backspace, but you can see how the…

I'm running a 5-star restaurant and I can only have the best items on my menu. My menu offers 6 items, each represented by a number from 1-6. If an item on my menu does not sell or does not sell that much compared to others, I must act and replace it with something that sells! Identify which dishes do not sell. If every dish sells, print the set of dishes that were ordered least. Input: A single line containing the dish number that were ordered. Treat as one number. INPUT: 156356231 Output: The list of dishes not ordered in numerical order. If every dish sells, print the set of dishes that were ordered least. Separate each number with a new line. OUTPUT: 4
In Java: Forms often allow a user to enter an integer. Write a program that takes in a string representing an integer as input, and outputs yes if every character is a digit 0-9. Ex: If the input is: 1995 the output is: yes Ex: If the input is: 42,000 or 1995! the output is: no Hint: Use a loop and the Character.isDigit() function.
In PYTHON, write a code that allows the user to input two non-negative number sequences in increasing order (the numbers entered are always getting bigger, and no number repeats), both terminated by a -1. The size of each sequence can vary. The output of this code should be a third sequence that is a combination of both sequences 1 and 2 and is sorted in non-decreasing order. Note: Non-decreasing order means there can be a repeated number in the third sequence (see example 1). A strictly increasing order sequence cannot have repeat numbers at all (see example 3). PLEASE do this using PYTHON, ONLY using while loops. NO language of "break", "len" or "True" please. Hint: we can use three separate lists to solve this code.
