Explanation / Answer

#include <iostream>
#include <iomanip>
using namespace std;

// create a function to print only the contents of the odd subscripts
// of array x; the numbers must be printed vertically on the screen.

void print_arrayx(int x[],int n)
{
     // use a for loop for printing

     for (int i = 0 ;i<n; i++)
      if(i%2==1)
        cout<<x[i]<<endl;
}

int main()

{
    // declare an array x with 40 subscripts
    int x[40];

    //initialize the contents of the even subscripts of x to x zero
    // and the odd subscripts of x to one. Use the start of the for loop below.
    // x[0] = 0, x[1] = 1, x[2] = 0, x[3] = 1 . . . . . .

    for(int i = 0 ;i<40;i++)
    {
      if(i%2==1)
        x[i] = 1;
      else
        x[i] = 0;
    }

// call the function print_arrayx and pass the array x to the function
    print_arrayx(x,40);

// create a for loop that will print the first 20 elements of the array.
    for(int i=0;i<20;i++)
      cout<<x[i]<<" ";
    cout<<endl;
return 0;
}
