Answer:
#include <iostream>
using namespace std;
int main()
{
 int input = 0;
 int count = 0;
 int sum = 0;
 int sumNegative = 0;
 while (true) {
  cout << "Enter a number: ";
  cin >> input;
  if (input == 0) break;
  count++;
  sum += input;
  if (input < 0) {
  	sumNegative += input;
  }
 }
 cout << "Count of the numbers: " << count << endl;
 cout << "Sum of all the numbers: " << sum << endl;
 cout << "Sum of the negative numbers: " << sumNegative << endl;
}
Explanation:
Your requirements regarding the sum and the negative numbers was a bit vague so I just did something you can probably adjust easily to your liking.

Answer:
144°
Explanation:
The sum of the measures of interior angles of a quadrilateral is 360°
The ratio of angle measures is 1:2:3:4
Total ratio = 1+2+3+4=10
The angles will be :
1/10 * 360°= 36°
2/10*360°=72°
3/10*360°=108°
4/10*360°=144°
The largest angle is 144°
