Explanation / Answer

Code:

#include<iostream>
#include<fstream>
using namespace std;
int main() {
int n=0, even=0, odd=0, sum=0,number;
float avg;
ifstream myReadFile;
string filename;
cout << "Enter the filename : ";
cin >> filename;
myReadFile.open(filename);
char output[100];
if (myReadFile.is_open()) {
while (!myReadFile.eof()) {
myReadFile >> output;
number = atoi(output);
if(number % 2 == 0){
even++;
}else{
odd++;
}
sum += number;
n++;
}
}
avg = sum/n;
cout << "The number of numbers in the file:" << n << endl;
cout << "The even numbers in the file: " << even << endl;
cout << "The odd numbers in the file: " << odd << endl;
cout << "The sum of all the numbers in the file: " << sum << endl;
cout << "The average of all the numbers in the file: " << avg << endl;
myReadFile.close();
return 0;
}
