C++ How do I initialize a clock to 0 and run it constantly throughout the program? THEN, how do I get the time at that moment multiple times? As in id like to set the

clock = 0,

do stuff

do stuff

get time now, store it

do stuff

get time now, store it

then also be able to do arithmetic on it, for instance, last time - current time = 2 seconds. I made it sound complicated but I believe this is very easy.

This is a Java program that I am having trouble making.

1- Search for the max value in the linked list.

2- Search for the min value in the linked list.

3- Swap the node that has the min data value with the max one. (Note: Move the nodes to the new positions).

4- Add the min value and the max value and insert the new node with the calculated value before the last node.

I already made a generic program that creates the linked list and has the ability to add and remove from the list. I am not sure how to create these generic methods though.

Below is my attempt to make the min finder, but it does not work and gives me an error on the bolded parts. It says "bad operand types for binary operator >".

public class Node<E> {

E element;

public Node(E data) {
this.element = data;
}   
}

/**

public class Driver {
public static void main(String[] args) {
LList<Integer> listy = new LList();
  
// adds 10 random numbers to the linkedlist
for (int i = 0; i < 10; i++) {

}
  
  
System.out.println("");

System.out.println("");
  
int max = listy.largestElement();
  
int min = listy.smallestElement();
  
System.out.println(max);
  
System.out.println(min);
//listy.remove(1);

I am not sure how to get these generic methods made.

C++

Drink Machine Simulator
Create a class that simulates and manages a soft drink machine. Information on each drink
type should be stored in a structure that has data members to hold the drink name, the
drink price, and the number of drinks of that type currently in the machine.
The class should have an array of five of these structures, initialized with the following data.

Drink Name      Cost   Number in Machine
Cola       1.00   20
Root beer          1.00       20
Orange soda    1.00       20
Grape soda      1.50 20
Bottled water    1.50       20

The class should have two public member functions, displayChoices (which displays a
menu of drink names and prices) and buyDrink (which handles a sale). The class should
also have at least two private member functions, inputMoney, which is called by buyDrink
to accept, validate, and return (to buyDrink) the amount of money input, and
dailyReport, which is called by the destructor to report how many of each drink type
remain in the machine at the end of the day and how much money was collected.

You may want to use additional functions to make the program more modular.
The client program that uses the class should have a main processing loop which calls the
displayChoices class member function and allows the patron to either pick a drink or
quit the program. If the patron selects a drink, the buyDrink class member function is
called to handle the actual sale. This function should be passed the patron’s drink choice.

Here is what the buyDrink function should do:
• Call the inputMoney function, passing it the patron’s drink choice.
• If the patron no longer wishes to make the purchase, return all input money.
• If the machine is out of the requested soda, display an appropriate “sold out” message and return all input money.
• If the machine has the soda and enough money was entered, complete the sale by updating the quantity on hand and money collected information, calculating any change due to be returned to the patron, and delivering the soda.

This last action can be simulated by printing an appropriate “here is your beverage” message.
Input Validation: Only accept valid menu choices. Do not deliver a beverage if the
money inserted is less than the price of the selected drink.

You would like to establish a WAN connectivity between your local offices across town. You are considering the use of a wireless solution. Complete and document research on the technology available to support the establishment of a WAN. Your document should address the following:

• At least 2 available solutions
• Benefits of this form of implementation
• Costs associated with the implementation of each solution
• A summary of 2–3 paragraphs stating which solution you have decided to implement and what motivated the decision

#1 Write a loop that displays every fifth number, 0 through 100.

#2 Write a do- while loop that asks the user to enter two numbers. The number should be added and the sum displayed. The user should be asked if he or she wishes to perform the operation again. if so, the loop should repeat; otherwise it should terminate.

#3 Write a nested loop that displays 10 rows of '#' characters. There should be 15 '#' characters in each row.

#4 Write a while loop that displays the odd numbers between 1 and 15.

#5 Write a program segment with a do-while loop that displays whether a user- entered integer is even or odd. The code should then ask the user if he or she wants to test another number. The loop should repeat so long as the user enters Y or y. Use a logical OR operator in the do-while loop test expression.

Suppose you are provided with an array of integer values. Write pseudocode for a program to determine how many unique values are in the array. Your solution should require time that is linearithmic in the size of the array.

(For example, if the array contains the values {1,3,4,1,2}, the answer is "4", because the array contains the values 1, 2, 3, and 4)
