Write the function void sort2(double* p, double* p) that receives two pointers and sorts the values to which they point. To test the function, write the main function that prompts the user to enter two values and then print out the sorted values. If you call sort2(&x, &y) then x <= y after the call.
The function illustrates the use of pointers.
Pointers are used to store address in programming languages such as C and C++.
The program in C language where comments are used to explain each line is as follows:
#include <stdio.h>
//This defines the function
void sort2(double* p1, double* p2){
//This declares a temporary variable t
double t;
//If p2 is less than p1,
if (*p2 < *p1) {
//The next 3 lines swap their values
t = *p2;
*p2 = *p1;
*p1 = t;
}
//This prints p1
printf("%f ", *(p1));
//This prints p2
printf("%f ", *(p2));
}
//The main method to test the function begins here
int main(){
double x = 23.0;
double y = 14.1;
sort2(&x, &y);
return 0;
}
//The program ends here

Assume that the speed of new computers costing a certain amount of money grows exponentially over time, with the speed doubling every 18 months. Suppose you need to run a very time consuming program and are allowed to buy a new computer costing a fixed amount on which to run the program. If you start now, the program will take 7 years to finish. How long should you delay buying the computer and starting the program so that it will finish in the shortest amount of time from now
Therefore, in order to run the program in the shortest time, you should delay for 3 years
Given that the speed of new computers costing a certain amount of money grows exponentially over time, with the speed doubling every 18 months.
Exponential equation as a function of time can be expressed as
P(t) = [tex]P_{0}[/tex][tex]R^{t/T}[/tex]
Quantity P will be increasing exponentially when R > 1. And it will decrease exponentially when R < 1.
Suppose you need to run a very time consuming program and are allowed to buy a new computer costing a fixed amount on which to run the program. If you start now, the program will take 7 years to finish.
Let the time required to run and complete a program for time t years be P(t).
If the speed doubling every 18 months, which is 3/2 years. This will eventually cause the running time to decrease by half (0.5)
P(t) = 7[tex](1/2)^{3t/2}[/tex] = 7[tex](2)^{-3t/2}[/tex]
The total time T will be sum of the delay time t and the time of running the program. That is
T(t) = t + P(t)
T(t) = t + 7[tex](2)^{-3t/2}[/tex] .......... (2)
We can calculate the minimum time t by differentiating the above equation and make it equal to zero.
dT/dt = 1 + 14/3[tex](2)^{-3t/2}[/tex](ln0.5) = 0
14/3[tex](2)^{-3t/2}[/tex](ln0.5) = -1
[tex](2)^{-3t/2}[/tex](ln0.5) = -3/14
[tex](2)^{-3t/2}[/tex] = -3/14ln0.5
Log (natural logarithm) both sides
-3t/2ln2 = ln(3/14ln2)
make t the subject of formula
t = - 3ln(3/14ln2) ÷ 2ln2
t = 2.5 approximately
To know how long you should delay buying the computer and starting the program so that it will finish in the shortest amount of time from now, substitute t into equation 2
T(2.5) = 2.5 + (7)[tex]2^{-3(2.5)/2}[/tex]
T(2.5) = 2.5 + 0.5202
T(2.5) = 3.02 years
T (2.5) = 3 years approximately
Therefore, in order to run the program in the shortest time, you should delay for 3 years

Answer:
a good algorithm must be able to accept a set of defined input. Output: a good algorithm should be able to produce results as output, preferably solutions. Finiteness: the algorithm should have a stop after a certain number of instructions. Generality: the algorithm must apply to a set of defined inputs.Explanation:
A good algorithm should have Steps, order, and outcomes. The correct option is C.
What is algorithm?An algorithm is a set of instructions that solves a particular problem or performs a specific task.
An algorithm must be well-defined and organised in order to be effective, with clear steps or procedures, a logical order of operations, and a clear understanding of the expected outcomes or results.
As a result, the steps, the order in which those steps are executed, and the expected outcomes or results of following those steps are three essential components of a good algorithm.
Option A describes the fundamental components of a programme, but it is not always a good algorithm.
Option B emphasises some important characteristics of good code, but not specifically related to algorithm design.

Creating an application for an ice cream shop. Create an interface named Flavor. Create three subclasses Lemon, Mint, and Chocolate. Create a class named Cone that has a single member variable named scoops of type List with a generic argument of Flavor. Initialize the scoops member variable to an object of one of the two list classes discussed during the lecture. Add a method named add with a single parameter of type Flavor named scoop. This will add the scoop object to the scoops list.
Create a class named IceCreamShop. The class has a single member variable of type Map named orders. Initialize this map to an instance of type HashMap. This map is used to track customer orders. It maps a customer name of type String to an instance of Cone. The map is modified by the following methods:
Add a method orderScoop(String customer, Flavor flavor). This method first checks if thereâs already an order for the given customer in the map. If the map does not have an entry with the customer name, a new entry is put into the map with a new Cone object. If the map already contains an entry, it gets the cone value from the map. Then it adds a new flavor to the cone. Note: Thereâs no need to put the cone back into the map because the map uses a reference to the cone object.
Add a method completeOrder(String customer). This method will return the cone for the given customer and remove the entry from the map.

What type of database replication relies on centralized control that determines when replicas may be created and how they are synchronized with the master copy
Database replication is very common in this Era. Traditional database replication is relies on centralized control that determines when replicas may be created and how they are synchronized with the master copy.
Database replication is known to be the constant electronic copying of data from a database using one computer or server that is connected also to a database in another . this ensure that all users do share the same level of information.
Replication is often done to technologies which are used for copying and distributing data and database objects from one database to another and thereafter use in synchronizing between databases.
Conclusively, Replicas can only be made in the Traditional database replication through the power of centralized control.

Partially-filled Arrays
Write the function rindby() which stands for remove mark>if not divisiby by. The function removes all elements from the array that are not evenly divisible by the argument n. You can find out if a number is evenly divisible by n using the remainder operator: % (there will be nothing left over).
The function returns the number of items removed or -1 if the array was originally empty.
The function takes 3 arguments:
the array of int that may be modified.
the size of the array (use size_t as the type)
the int n used to check for divisibility
Here are two short examples:
int a[] = {2, 3, 4, 5, 6};
size_t size = 5;
int removed = rindby(a, size, 2);
// removed->2, a = [2, 4, 6], size = 3
size = 0;
removed = rindby(a, size, 3);
// removed-> -1, no change otherwise
In the first case, the numbers 3 and 5 are removed because they are not divisible by 2. Only the numbers that are divisible by 2 are left in the array.
In the second, size has been set to , so the input array is empty and the function returns - 1.

1. Where did the Industrial Revolution start and why did it begin there?
Answer:
The first Industrial Revolution began in Great Britain in the mid-to-late 1700s, when innovation led to goods being produced in large quantities due to machine manufacturing.
This process began in Britain in the 18th century and from there spread to other parts of the world. Although used earlier by French writers, the term Industrial Revolution was first popularized by the English economic historian Arnold Toynbee (1852–83) to describe Britain's economic development from 1760 to 1840.
