Code:
#include <iostream>
#include <fstream>
using namespace std;
int main ()

	int i;
	int A[20];
	
	float sumPos;
	float sumNeg;
	
	in_file >> i;

	{
		if (i < 0)
		sumNeg += A[i];
		
		else sumPos += A[i];
	}
	in_file >> i;
	}
		
	cout << "Sum of Positive Integers = " << sumPos << endl;
	cout << "Sum of Negative integers = " << sumNeg << endl;
