Answer:
Here is the Array class named Number:
#include <iostream>
#include <iomanip>
using namespace std;
class Number {
private:
int size;
float *ptr;
float num;
public:
Number(){
cout<<"Enter size of array: ";
cin>>size;
ptr = new float[size];
cout<<"Enter elements"<<endl;
for(int i=0;i<size;i++) {
cin>>ptr[i]; } }
void getNumbers(){
cout << "{ ";
for (int i = 0; i < size; i++) {
cout <<ptr[i] <<setprecision(2)<< " "; }
cout << "}"; }
Number(int s){
ptr = new float[s];
size = s;
for (int i = 0; i < size; i++) {
cout << "Enter elements : ";
cin >> num;
ptr[i] = num; } }
~Number(){
delete [] ptr; }
void storeNumber(int input, float num){
while (input < 0 || input > size-1) {
cout << "array size exceeded! Enter an element again " << endl;
cin >> input;
if (input >= 0 && input < size) {
ptr[input] = num;
break; } }
if (input >= 0 && input < size) {
ptr[input] = num; } }
void retrieveNumber(int position){
while (position < 0 || position > size-1) {
cout << "array size exceeded! Enter an element again " << endl;
cin >> position;
if (position >= 0 && position < size) {
cout << "The number at "<<position<<"is: " << ptr[position];
break; } }
if (position >= 0 && position < size) {
cout << "The number at "<<position<<" is: " << ptr[position]; } }
float HighestNumber(){
float highest = ptr[0];
for (int i = 1; i < size; i++) {
if (ptr[i] > highest) {
highest = ptr[i]; } }
return highest; }
float LowestNumber(){
float lowest = ptr[0];
for (int i = 1; i < size; i++) {
if (ptr[i] < lowest) {
lowest = ptr[i]; } }
return lowest; }
float AverageNumber(){
float avg = 0.0;
for (int i = 0; i < size; i++) {
avg += ptr[i]; }
return avg/size; }
};
int main() {
Number array;
array.getNumbers();
cout << endl;
int pos;
float no;
cout << "Choose an element to replace: ";
cin >> pos;
cout << "What number do you want to replace element with?" << endl;
cin >> no;
array.storeNumber(pos, no);
array.getNumbers();
cout << endl;
int pos1;
cout << "Enter an element to retrieve the number: ";
cin >> pos1;
cout << endl;
array.retrieveNumber(pos1);
cout << endl;
cout << endl;
cout << "The highest number is: " << array.HighestNumber() << endl;
cout << "The lowest number is : " << array.LowestNumber() << endl;
cout << "Average of all numbers is : " << array.AverageNumber() << endl;
cout << endl;
return 0; }
Explanation:
The program is well explained in the comments mentioned with each line of code in the attached document.
The screenshot of the program along with its output is attached.
Using the knowledge in computational language in C code it is possible to write a code that organizes and calculates the value of the matrix of A*A and that is in up to 4 decimal places.
<h3>Writing the code in C is possible:</h3>
<em>A=[1 2 2;3 4 5;6 7 8];</em>
<em>[u ,s ,v] = svd(A);</em>
<em>k = 1;</em>
<em>A1 = u(:,1:k)*s(1:k,1:k)*v(:,1:k)'; %'</em>
<em>RMSE = rms(sqrt(mean((A - A1).^2)))</em>
