Question

I am having trouble figuring out what should go in the place of "number" to make the loop stop as soon as they enter the value they put in for the "count" input. I am also having trouble nesting a do while loop into the original while loop (if that is even what I am supposed to do to get the program to keep going if the user wants to enter more numbers???) I have inserted the question below, as well as my coding.

Question:  

In this program you will calculate a sum of numbers that are entered by the user. This program should use while loops and do-while loops to accomplish several tasks (DO NOT USE A FOR LOOP FOR THIS ASSIGNMENT).

• After displaying a welcome screen, ask the user how many numbers they would like to add together. (*This number will be used to display the index of each number received from the user. ie. Enter Number 1: X …. Enter Number 2: X ….)

• Using a while loop, allow the user to enter each number, keeping the total and displaying the count as they are entered (shown above).

• Once the user has entered all of their numbers, display the final sum of their input.

• After displaying the sum, ask the user if they would like to sum up another set of numbers by entering ‘Y’ for Yes or any other letter for No.
• If they choose Yes, repeat the program. If they choose No, display a message stating that the program will end and end the program.

My Coding:

// This is a program that will perform calculations based on user input
#include <iostream>
#include <iomanip>

using namespace std;

int main()
{

int count; // Total amount of numbers to add together
int number; // user's number input
int total = 0; // Accumulator
char Y;
char N;
char answer; // Y or N to keep adding numbers

while (number <= count)
{
cout << "Welcome to the SUM Program!" << endl;
cout << "" << endl;
cout << "How many numbers would you like to add together?" << endl;
cin >> count; // Amount of numbers they want to add
cout << "Enter your numbers below." << endl;
cout << "" << endl;
cout << "Enter Number: " << endl;
cin >> number;
number++;
}

do
{
cout << "The sum of all your numbers is " << total << endl;
cout << "" << endl;
cout << "Would you like to find the sum of a new set of numbers?" << endl;
cout << "Enter Y for Yes and N for No." << endl;
cin >> answer;
}

while (answer == N)

{
cout << "" << endl;
cout << "Thanks for using the SUM program! Goodbye!" << endl;
}

return 0;
}

Answer:

Program:

#include <iostream>
using namespace std;
int main()
{
/* 'sum' is for storing the sum of numbers, 'n' is for total number of integers,
'num' is for storing the current number, 'i' is the counter variable */
int sum,n,num,i;
char answer; /* 'answer' is for storing 'Y' or 'y' */
do /* do-while loop starts here */
{
   cout<<"Welcome to the SUM Program!"<<endl;
   cout<<"how many numbers you would like to add together? ";
   cin>>n; /* reads the number of integers into 'n' */
   cout<<"Enter your numbers below"<<endl;
   i=1; /* initialising 'i' by 1 (first number) */
   sum=0; /* 'sum' has the initial value 0 */
   while(i<=n) /* when i<=n, while loop repeats */
   {
       cout<<"Enter Number "<<i<<":";
       cin>>num; /* reading the current number into 'num' */
       sum=sum+num; /* calculating the 'sum', by adding the current 'num' to previous 'sum' */+
       i++; /* increments 'i' (next number) */
   }
   cout<<"The sum of all your numbers is "<<sum<<endl; /* displaying 'sum' */
   cout<<"Would you like to find the sum of a new set of numbers?"<<endl;
   cout<<"Enter Y for Yes and N for No"<<endl;
   cin>>answer; /* taking a character into 'answer' */
}while(answer=='Y'||answer=='y'); /* if 'answer' has the value 'Y' or 'y', do-while loop repeats, otherwise jump the loop */
cout<<"Thanks for using the SUM program! Goodbye!"<<endl;
return 0;
}
