2 One-Dimensional Array Data Types with Integer Indexes
Program Reverse is used for Exercises 1-2.
// Program Reverse reads numbers into an array
// and prints them out in reverse order.
#include <iostream>
#include <fstream>
using namespace std;
const int MAX = 10;
int main ()
{
int numbers[MAX];
ifstream inData;
int value;
int index;
inData.open ("reverse.dat");
for (index = 0; index < MAX; index++)
{
// FILL IN code to read value from file
// FILL IN code to store value into numbers
}
for (index = MAX - 1; index >= 0; index--)
// FILL IN code to write numbers on the screen
return 0;
}
Exercise 1.
Fill in the missing code in program Reverse. Put the following data in file reverse.dat. Run the program
and show the results displayed on the screen.
