NEED HELP WITH FINAL PROJECT

[WALIA794]

Hey guys,
I have a final project due in three days and I cant get arrays, If someone can help you out, It will be highly appreciated. I have all the details and my code in here. The main problems are the ARRAYS with their CASE.
Thank you

/* Write a program that implements the following functions:
double add( double, double ) - function that returns the sum of 2 numbers.
double sub( double, double ) - function that returns the difference of 2 numbers.
double mul( double, double ) - function that returns the product of 2 numbers.
double div( double, double ) - function that returns the quotient of 2 numbers.
If the function attempts to divide by 0, it should return 0 instead.
double add( double[], int ) - function that accepts an array of doubles and the size of the array.
It returns the sum of all the elements of the array. This is an overloaded function.
double avg( double[], int ) - function that accepts an array of doubles and the size of the array.
It returns the avg of all the elements of the array.
void sort( double[], int ) - function that accepts an array of doubles and the size of the array.
The function sorts the array using the sorting algorithm of your choice.
int search( double[], int, double) - function that accepts an array of doubles, the size of the array, and a value to search for.
Returns the position within the area if target found, -1 otherwise.
void save( double[], int ) - function that accepts an array of doubles and the size of the array.
Writes all of the values inside the array to a text file on disk.
UPDATED!!!!
void print( double[], int ) - a function that accepts an array of doubles and the size of the array.
Displays all the values inside the array to the screen.

int main() should implement a menu from which the user may select an option:
(+) Add Two Values
(-) Sub Two Values
(*) Mul Two Values
(/) Div Two Values
(I) nput Values
(P)rint Values
(S)um Array
S(o)rt Array
S(e)arch Array
(A)vg of Array
(Q)uit
Based on the user's selection, the appropriate function will be called and output displayed.
The user should be able to select options repeatedly until the user decides to quit.
You are free to decide the length of the array. It can be static or dynamic.
A do-while loop and switch statement might be easiest, but you are free to implement your
solution as you wish using concepts covered during the course.
Input validation: The program should only accept valid menu selections.*/

#include <iostream>
#include <iomanip>
#include <fstream>
using namespace std;

// Functions
void selection();
double AVG(double arr[], int size);
int main()
{

int selection;
double X;
double Y;

// Constants for the menu.
const int ADD = 1;
const int SUB = 2;
const int MUL = 3;
const int DIV = 4;
const int INPUT = 5; // An input array.
const int PRINT = 6; // A print array.
const int SUM = 7; // A sum array.
const int SORT = 8; // A sort array.
const int SEARCH = 9; // A search array
const int AVG = 10; // An average array.
const int QUIT = 11;

// Constants for ADD, SUB, MUL, DIV
int X; // value for X
int Y; // value for Y

// Variable Formulas
double result;

// Numeric Output Formatting.
cout << fixed << showpoint << setprecision(2);

do
{
// Display the menu.
cout << "What would you like to do:\n"

<< "8. Sort the set of numbers\n"
<< "9. Find sum of set of numbers\n"
<< "10.Find the average of set of numbers\n"
<< "11. Quit the program\n";
cin >> selection;

// Validate the Menu Selection.
while (selection < ADD || selection > QUIT)
{
cout << "Please enter a valid menu choice: \n";
cin >> selection;
}

// Process the menu choice.
if ( selection != QUIT)
{
// Get the value for X and Y.
cout << " Please enter a value for X: \n";
cin >> X;

cout << " Please enter a value for Y: \n";
cin >> Y;

// Respond to the menu choice.
switch (selection)
{
case ADD:
result = X + Y;
break;
case SUB:
result = X - Y;
break;
case MUL:

break;
case DIV:

if (Y = 0) result = 0;
break;
case INPUT:

case PRINT:

case SUM:

case SORT:

case SEARCH:

case AVG:

// Display the answer
cout << "The result is :" << result << endl;
}

return 0;

Hi @WALIA794,

This is my
approach i
hope this may
help you.
