Code examples

The following code example fails the check and will give a warning:

int example(int n) {
  int i;           // Non-compliant
  i = n + 1;
  return i;
}

The following code example passes the check and will not give a warning about this issue:

int example(int n) {
  int i = n + 1;   // Compliant
  return i;
}
