Program 8-3
1 // This program reads employee work hours from a file and stores them
2 // in an int array. It uses one for loop to input the hours and another
3 // for loop to display them.
4 #include <iostream>
5 #include <fstream>
6 using namespace std;
7
8 int main()
9 {
10 const int NUM_EMPLOYEES = 6; // Sets number of employees
11 int hours[NUM_EMPLOYEES]; // Holds each employee's hours
12 int count; // Loop counter
13 ifstream datafile; // Used to read data from a file
14
15 // Open the data file
16 datafile.open("work.dat");
17 if (!datafile)
18 cout << "Error opening data file\n";
19 else
20 { // Input hours worked by each employee
21 for (count = 0; count < NUM_EMPLOYEES; count++)
22 datafile >> hours[count];
23 datafile.close();
24
25 // Display the contents of the array
26 cout << "The hours worked by each employee are\n";
27 for (count = 0; count < NUM_EMPLOYEES; count++)
28 { cout << "Employee " << count+1 << ": ";
29 cout << hours[count] << endl;
30 }
31 }
32 return 0;
33 }
