Integer in is read from input. Write a while loop that reads integers from input until a positive integer is read. Then, find the sum of all integers read. The positive integer should not be included in the sum.

Ex: If the input is -42 -31 -39 -26 21, then the output is:

-138

#include using namespace std; int main() { int in; int intSum;

intSum = 0; cin >> in;

/* Your code goes here */

cout << intSum << endl;

return 0; }
