Porblem in my code

[Mohamed Waly]

Hi there,
I am writing a program that prints the sum of even and odd numbers and here is my code
#include <iostream>

using namespace std;

const int SENTINEL = -999;

int main() {
int integers = 0;
int even = 0;
int odd = 0;

cout << "Enter an integer ending with -999: " << endl;

while (integers != SENTINEL) {
cin >> integers;
if (integers % 2 == 0) {
even = even + integers;
}
else {
odd = odd + integers;
}
}

cout << "The sum of your even integers is: " << even << endl;
cout << "The sum of your odd integers is: " << odd << endl;

return 0;
}


but now in the output it adds -999 to the odd numbers
How can I overcome this problem?

You could break from loop just after reading a value, if the new value is the sentinel.

#include <iostream>

using namespace std;

const int SENTINEL = -999;

int main() {
int integers;
int even = 0;
int odd = 0;

cout << "Enter an integer ending with -999: " << endl;

while ( cin >> integers && integers != SENTINEL) {
if (integers % 2 == 0) {
even = even + integers;
}
else {
odd = odd + integers;
}
}

cout << "The sum of your even integers is: " << even << endl;
cout << "The sum of your odd integers is: " << odd << endl;

return 0;
}
