Solution

#include <iostream>
#include <fstream>
using namespace std;

int main()
{
ofstream outputFile;
outputFile.open (\"sum.txt\");
ifstream inputFile1;
inputFile1.open(\"1030Prob2a.txt\");
ifstream inputFile2;
inputFile2.open(\"1030Prob2b.txt\");
double n1, n2;
if (inputFile1.is_open() && inputFile2.is_open()) {
while (!inputFile1.eof() || !inputFile2.eof()) {
n1 = 0;
n2 =0;
inputFile1 >> n1;
inputFile2 >> n2;
outputFile << (n1 + n2)<<endl;

}
}
cout<<\"File has been generated\"<<endl;
inputFile1.close();
outputFile.close();
return 0;
}
