Code examples

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

struct Pair { int a; int b; };

int example()
{
  Pair p {};
  p.a = 2;
  p.a = 3;
  return p.a;
}

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

struct Pair { int a; int b; };

Pair example()
{
  Pair p {};
  p.a = 2;
  p.b = 3;
  return p;
}
