Thread: One more program help?

Hello if anyone could help me with this code, I would appreiciate. It asks for us to use CMDline arguments and swap the elements of an array in reverse order. for example (2 3 4 5 6) is (6 5 4 3 2).
Here is my code.

Code:

#include <iostream>
#include <stdlib.h>

using namespace std;
int reverse(int numpts, int array[])
{
     int temp;
for (int i=0; i < numpts/2; i++) 
    {
        temp = array[i];
        array[i] = array[numpts-i-1];
        array[numpts-i-1] = temp;
    }
    return temp;
}
int main(int argc, char *argv[])
{
  int npts = argc - 1;
  int x[50];
  for (int i = 1; i < argc; i++)
  {
  x[i-1] = atoi(argv[1]);
 cout << argv[i] << endl;
 } 
  cout << reverse (npts, x) << endl; 
  system("PAUSE");	
  return 0;
}

thanks, i think im still stuck though im still fresh in programming?
is this any better? thanks.

Code:

#include <iostream>
#include <stdlib.h>

using namespace std;
int reverse(int numpts, int array[])
{
     int temp;
for (int i=0; i < numpts/2; i++) 
    {
        temp = array[i];
        array[i] = array[numpts-i-1];
        array[numpts-i-1] = temp;
    }
    return temp;
}
int main(int argc, char *argv[])
{
  int npts = argc - 1;
  int x[50];
  for (int i = 1; i < argc; i++)
  {
  x[i-1] = atoi(argv[i]);
 cout << argv[i] << endl;
 x[i-1] = reverse (npts, x);
 cout << x[i-1] << endl; 
 
 } 
  system("PAUSE");	
  return 0;
}

how is this any better?

Code:

#include <iostream>
#include <stdlib.h>

using namespace std;
void reverse(int numpts, int array[])
{
     int temp;
for (int i=0; i < numpts/2; i++) 
    {
        temp = array[i];
        array[i] = array[numpts-i-1];
        array[numpts-i-1] = temp;
    }
}
int main(int argc, char *argv[])
{
  int npts = argc - 1;
  int x[50];
  for (int i = 1; i < argc; i++)
  {
  x[i-1] = atoi(argv[i]);
 cout << argv[i] << endl;
 reverse (npts, x);
 cout << x << endl; 
 } 
  system("PAUSE");	
  return 0;
}
