Can someone help me understand why the output file prints an extra number 1, even though the input does not have one. I do not understand why it is adding an extra number what I want it to do is just reprint the input again on the output #include #include #include using namespace std; int getNumber(ifstream& infile, ofstream& outfile){ int num; infile >> num; outfile << setw(5) << num << " "; return num; } void classifyNumber(ifstream& infile,int&even,int&odd,int&zero){ int num; while(!infile.eof( )){ infile >> num; if (num % 2 == 0) { even++; if (num == 0) zero++; } else odd++; } } void printResult(ofstream& outfile,int& even,int& odd,int& zero,int& sum,double& average ){ outfile << endl; outfile << "There are " << even << " even numbers." << endl; outfile << "There are " << odd << " odd numbers" << endl; outfile << "Total number of zeroes:" << zero << endl; outfile << "Sum of numbers:" << sum << endl; outfile << "Average of numbers:" << average; cout << "There are " << even << " even numbers." << endl; cout << "There are " << odd << " odd numbers." << endl; cout << "Total numbers of zeroes:" << zero << endl; cout << "Sum of numbers:" <
