Exercise 1

Flexible Count-controlled `while` Loop Exercise:

Create a C++ program ex1_count.cpp wih the the following code in the Visual Studio project or copy the following code into your IDE:

// Program Count prompts for the number of integers to sum.
// It then reads the integers in a loop, summing them.
// Finally, it prints the sum.

#include <iostream>
using namespace std;

int main ()
{
    int  sum = 0;                 // summing variable
    int  dataValue;               // input value

// Add code: Declare an int here for the loop counter

// Add code: Declare an int here for the loop total

// Add code: Set the loop counter to 0

// Add code: Prompt the user for how many numbers they want to add
    //           ie. the loop total

// Add code: Read the loop total

// Add code: Write a while statement that compares
    //           your loop counter to your loop total
    //             eg. while (loopctr < looptotal)
    //           Note: the variable names depend on how you declared them.

{
        cout  << "Enter an integer value.  Press return." << endl;
        cin  >> dataValue;
        sum = sum + dataValue;

// Add code: Increment your loop counter variable

}  // end of while loop block

cout  << endl << "The sum is "  << sum  << endl;

return 0;
}

When it is complete, this program will allow the user to add together any number of integers. It will use a while with two variable - one for the loop counter, and one for the total number of loop repetition. The user first types how many numbers they wish to add, then types the numbers one at a time pressing enter after each one.

Instructions:

Read the code carefully, paying attention to the comments.
Complete the program by adding one line of code after every "Add code: " comment.
Compile and run the program. Use the the following input values to test your program:
loop total: 5
five numbers to be added 3, -2, 0, 9, 1.

Your output should look like this:


Please input the number of integers that you would like to add:   5
Enter an integer value: 3
Enter an integer value: -2
Enter an integer value: 0
Enter an integer value: 9
Enter an integer value: 1
The sum of the 5 integers is 11

If that worked, test design a second test for your program with 3 or 4 input integers of your choice.

When you are done:

Take a screenshot of your IDE and console window after compiling the code and then running the program twice:
1. with the test data above
2. with your own test data
For this exercise, you will have: ex1_count.cpp.
Complete all the exercises in this lab and upload the .cpp files and screenshots to URCourses.
