While statement

Description

Write a program that will compute the sum of one or more data values entered by the user. First, the program will ask the user to provide the data count. Then it will ask the user data count times to enter a data value. It will then display the sum of data values entered by the user. See the Test section below for test data.

Requirements

Do this assignment using a While statement.

Test

For turning in the assignment, perform the following test run using the input shown.

(The user input is shown in bold)

Test Run

Enter data count

5

Enter a data value:

10

Enter a data value

50

Enter a data value

40

Enter a data value

20

Enter a data value

30

Sum: 150

(Above, user input is shown in bold)

Submit

Sample Code

//variable declarations

//The variable below contains the running sum.

//It contains the sum of all the values entered by the user so far.

double sum;

//The variable below contains user input.

//It contains the most recent value entered by the user

double num;

//The variable below contains the data count.

//It contains the number of values the user is going to enter.

//It contains the number of times the While loop should loop (go around).

int dataCount;

//The variable below contains the loop count.

//It contains the number of times the While loop have looped (gone around) so far.

int count;

//input data count

cout << "Enter data count" << endl;

cin >> dataCount;

//initialize sum

sum = 0;

//Initial Setup

count = 0;

//Test

while (count < dataCount)

{

//input a number

cout << "Enter a data value" << endl;

cin >> num;

//add num to sum (add a code line below)

//Update Setup

count = count + 1;

}

//display sum (add a code line below)
