I hope I did the code tags correctly:

1st I need to change the output to a file

2nd additional programming to find the sum and average of the number

3rdchange print result to print to a file

This is not an assigned homework just another example I want to try to figure out.

//code

//codeCode://Program: Classify Numbers //This program counts the number of zeros, odd, and even numbers #include <iostream> #include <iomanip> using namespace std; const int N = 20; //Function prototypes void initialize(int& zeroCount, int& oddCount, int& evenCount); void getNumber(int& num); void classifyNumber(int num, int& zeroCount, int& oddCount, int& evenCount); void printResults(int zeroCount, int oddCount, int evenCount); int main () { //Variable declaration int counter; //loop control variable int number; //variable to store the new number int zeros; //variable to store the number of zeros int odds; //variable to store the number of odd integers int evens; //variable to store the number of even integers initialize(zeros, odds, evens); //Step 1 cout << "Please enter " << N << " integers." << endl; //Step 2 cout << "The numbers you entered are: " << endl; for (counter = 1; counter <= N; counter++) //Step 3 { getNumber(number); //Step 3a cout << number << " "; //Step 3b classifyNumber(number, zeros, odds, evens); //Step 3c }// end for loop cout << endl; printResults(zeros, odds, evens); //Step 4 return 0; } void initialize(int& zeroCount, int& oddCount, int& evenCount) { zeroCount = 0; oddCount = 0; evenCount = 0; } void getNumber(int& num) { cin >> num; } void classifyNumber(int num, int& zeroCount, int& oddCount, int& evenCount) { switch (num % 2) { case 0: evenCount++; if (num == 0) zeroCount++; break; case 1: case -1: oddCount++; } //end switch } void printResults(int zeroCount, int oddCount, int evenCount) { cout << "There are " << evenCount << " evens, " << "which includes " << zeroCount << " zeros" << endl; cout << "The number of odd numbers is: " << oddCount << endl; }
