Hi ,

void accstrn();
int a [30];   // its a predefined array of 30 allocations.
int  c ;                // counter variable.
void main()

{

 clrscr();

 accstrn();

 printf ( " The length of the Int Array is %d ",c);
 
 getch();

}

void accstrn()
{
 

  for ( int i=0 ; i < 30 ; ++i )
 {
  scanf (" % d ", & a[i]);
  
  if ( a[i] != 0 )
 
  {
 
    c = i;
   
   accstrn ();
  }
  else
  {
   

   return (c);
  }
 }
}
