Filename: numbers.cpp

Write a program that will allow the user to enter a set of integers (as many as they want), then prints out a summary of information, as follows:

Prompt the user continually to enter a number using a loop, until the value 0 is entered, which will be the signal to stop entering values. (This is sometimes known as a "sentinel" value).

Once the sentinel value has been entered, print out the following information:

The number of positive values that were input

The number of negative values that were input

The sum of the input values

The average (to two decimal places) of the input values

Your output must match mine exactly. See the sample runs below

Explanation / Answer

#include <iostream>

#include <iomanip>

using namespace std;

int main() {

// declaring variables

int positive = 0, negative = 0, sum = 0, count = 0, number;

double average = 0;

// taking first input

cout << "Enter a Number (0 to stop): ";

cin >> number;

while(number != 0)

{

// updating number of positive and negative numbers

if(number > 0)

positive++;

else

negative++;

sum+= number;

// taking input

cout << "Enter a Number (0 to stop): ";

cin >> number;

// incrementing count by 1

count++;

}

// setting average

if(count > 0)

average = sum/(count*1.0);

// printing output

cout << endl << "# of positives = " << positive;

cout << endl << "# of negatives = " << negative;

cout << endl << "Sum = "<< sum;

cout << endl << fixed << setprecision(2) << "Average = " << average;

}

/*SAMPLE OUTPUTS

Enter a Number (0 to stop): 12

Enter a Number (0 to stop): 4

Enter a Number (0 to stop): -1

Enter a Number (0 to stop): -5

Enter a Number (0 to stop): 18

Enter a Number (0 to stop): 0

# of positives = 3

# of negatives = 2

Sum = 28

Average = 5.60

Enter a Number (0 to stop): 4

Enter a Number (0 to stop): 8

Enter a Number (0 to stop): 24

Enter a Number (0 to stop): 94

Enter a Number (0 to stop): -1

Enter a Number (0 to stop): 43

Enter a Number (0 to stop): 13

Enter a Number (0 to stop): 0

# of positives = 6

# of negatives = 1

Sum = 185

Average = 26.43

Enter a Number (0 to stop): 0

# of positives = 0

# of negatives = 0

Sum = 0

Average = 0.00
