File I/O and While Statement
I have an assignment due at 8:00PM. I've had a ton of work to do this week and haven't really got to learn the topic before the assignment. I'm just trying to get the points for the assignment and learn the stuff after its due.
You are to create a program that will read 50 integers from a file and sum them together. Output this sum to an output file. You will also output (to the file) how many numbers were odd, and how many were even (zeros may be considered even). Your program MUST employ a while loop to read the values from the file.
The while loop should check for TWO things (what are they?). Hint: you know you need to read 50 numbers, but for correct file processing, what else should you check for? Your grade will be based on whether or not you correctly identify both conditions to be used in the while loop.
here's my code so far:
#include <iostream> // Preprocessor directive for cin and cout
using namespace std;
int main ()
// Declaring variables
int number(0), even(0), odd(0), count(0);
int sum, num;
cout << "Error opening file\n";
while ( !num_list.eof())
while (count <= 50)
sum += num_list;
num_list >> number;
while (number >= 0 && number <= 50)
if (num % 2 == 0)
even = even + number;
odd = odd + number;
cout << "The file contains " << even << "even numbers.\n";
cout << "The file contains " << odd << "odd numbers.\n";
I am getting error: no match for 'operator+=' in 'sum += num_list'
I have been trying for hours, but can't seem to get it just right. I hate to ask this, but if someone could fix this and post it that would be great, as I really need the points.
Thanks in advance if anyone tries to help!
