Question

Please Help! Write a C++ program to read integers until 9999 is entered (called sentinel – sentinel is used to indicate the end of input and must not to be considered as the valid data for the computation). Perform the following operations for the integers entered by the user.

Display the sum of the numbers less than 100

Display the smallest of the positive integers

Display the largest of the negative integers

Display how many integers are between 100 and 999

I wrote the following code however for the minimum I am getting zero. How can I get the actual minimum and not zero.

#include

using namespace std;

int main() {

int number;

int sum = 0;

int maximum = 0;

int minimum = 0;

int hundredto999 = 0;

while (true) {

cout << "Enter whole number. Enter 9999 to exit: ";

cin >> number;

if (number == 9999) {

break;}

if(number < 100) sum = sum + number;

if(number > 0 && (number == 0 || number < minimum)) minimum = number;

if(number > 0 && (number == 0 || number > maximum)) maximum = number;

if(number >= 100 && number <= 999) ++hundredto999;

}

cout << "The sum of numbers less than 100 is: " << sum << endl;

cout << "The smallest number is: " << minimum << endl;

cout << "The largest number is: " << maximum << endl;

cout << "The sum of number from 100 to 999 is: " << hundredto999 << endl;   

return 0;

}

Answer 1

#include <iostream>

using namespace std;

int main()

{

int number;

int sum = 0;

int negMax;

int posMin;

int hundredto999 = 0;

cout << "Enter a Positive number: ";

cin >> posMin;

cout << "Enter a Negative number: ";

cin >> negMax;

if(posMin>=100 && posMin<=999)

hundredto999++;

if(posMin<100)

sum=posMin+negMax;

else

sum=negMax;

while (true)

{

cout << "Enter whole number. Enter 9999 to exit: ";

cin >> number;

if (number == 9999)

break;

if(number < 100)

sum = sum + number;

if(number >=0 && number<posMin)

posMin = number;

if(number < 0 && number>negMax)

negMax = number;

if(number >= 100 && number <= 999)

++hundredto999;

}

cout << "The Sum of numbers less than 100 is: " << sum << endl;

cout << "The Smallest Positive number is: " << posMin << endl;

cout << "The Largest Negative number is: " << negMax << endl;

cout << "The Count of numbers between 100 to 999 is: " << hundredto999 << endl;

return 0;
