Find record index

Step5: Defining the search(student[] st, int itemcount) method to search for the index of a target record. This method is useful as we need it to find the location of the target record in the array of student objects. It can help us to make sure the record does exit before we allow the record for deletion or updating. If the target element is found, the method returns the index of this element. It return -1, if the target element is not found in the array.

static int search(student[] st, string id,int itemcount){
int found =-1;
for (int i = 0; i < itemcount && found==-1; i++)

  if (st[i].stnumber == id) found=i;

  else found=-1 ;

return found;
