Question

Must be written in c++

Must display comments

Write a program that will read monthly sales into a dynamically allocated array allocated array of double values.

Your program should:
- prompt the user to enter the size of the array ( that is the number of monthly sales)
- dynamically allocate an array large enough to hold the number of monthly sales given
by the user
- find and print the yearly sum of all the monthly sales

Note: don’t forget to deallocate memory!

Sample Run:

Enter the number of monthly sales to be input: 4
Enter the monthly sales for month 1: 1290.89
Enter the monthly sales for month 2: 905.95
Enter the monthly sales for month 3: 1567.98
Enter the monthly sales for month 4: 994.83
The total sales for the year is: $4759.65

`Hey,

Note: Brother in case of any queries, just comment in box I would be very happy to assist all your queries

#include<iostream>

using namespace std;

//sutting up prototypes

double findYearlySum(double sales[],int n);

//main function

int main()

{

//declaration

double *sales;

int arraysize;

cout<<"Enter the number of monthly sales to be input: ";

cin>>arraysize;

//dynamic creation of array

sales=new double[arraysize];

cout<<"Enter Monthly Sales"<<endl;

//reading monthly sales

for(int i=0;i<arraysize;i++)
{
cout<<"Enter the monthly sales for month "<<(i+1)<<": ";
cin>>sales[i];
}
//calling yearly sum function

double sum=findYearlySum(sales,arraysize);

//calling average function

//display result

cout<<"The total sales for the year is: $"<<sum<<endl;

delete sales
;

}//end of main

//function definition for finding sum

double findYearlySum(double *sales,int n)

{

double sum=0;

for(int i=0;i<n;i++)

sum +=sales[i];

return(sum);

}

Kindly revert for any queries

Thanks.
