Coding standards

Code examples

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

struct example {
  int x;
  int y;
};

struct example object = { .x = 100, .x = 200 };
// object = { .x = 100, .y = 0 };

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

struct example {
  int x;
  int y;
};

struct example object = { .x = 100, .y = 200 };
// object = { .x = 100, .y = 200 };
