In this program I have to write a program that has to take the inputs of a file and output the average of the sum of numbers. My question is regarding how to average the numbers by adding the total numbers in the file. Would I have to do a count?

Code:#include <fstream>#include <iostream> int main() { using namespace std; ifstream in_stream; cout << "I am going to take the numbers from the input file and average them." << endl; in_stream.open ( "input.dat" ); if ( in_stream.fail( ) ) { cout << "Please check if the file is saved properly. It could not open." << endl; } double first_number, next_number, total_numbers; int count = 0; in_stream >> first_number >> next_number >> total_numbers; first_number = 0; next_number = first_number + next_number; cout << "The average of the numbers is "; cout << ( first_number + next_number ) / total_numbers << endl; in_stream.close (); cout << "The program will now close." << endl; }
