Designated Initializers for Structures
Designated initializers allow you to initialize structure members by name rather than by position. This makes code more robust against changes in the structure definition and improves readability by explicitly stating which value belongs to which field.

Breakdown
1
.mode = 'A',
Explicitly assigns 'A' to the 'mode' member using the dot operator.
2
struct Config sys_cfg = { ... };
Initializes the struct instance in a single, clear block.
