Is there any Stray or Dangling Pointers in this program?

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

int array(int *x);

int main(int argc, char** argv) 
{
    int x[10];
    int y[10];
    
    array(x);
    array(y);
   
    for(int i=0;i<10;i++)
    cout << " x: " << *(x+i);
    cout << endl;
    
    for(int i=0;i<10;i++)
    cout << " x: " << *(y+i);
    cout << endl;
    
    return 0;
}

int array(int *x)
{
   for(int i=0;i<10;i++)
       *(x+i)=i;
}

No, you are fine.

Just fyi:

*(x+i)  // <- this
x[i] // <- is the same as this

// most people find the latter to be more readable.

Is it possible to pass an array by reference?

[Disch]

Yeah... that's basically what you're doing.

You can't pass them by value. At least not without putting them in some kind of container (like a struct or something).
