Cannot copy string of mismatching length into array

[jaybdub]

The following does not compile

typedef struct _Simple {
    bool has_name;
    char name[20];
} Simple;

Simple msg;
msg.name = "Bob"

Error is something like :

char[3] cannot be set to char[20].

Instead, use strcpy of strncpy (which adds overflow protection I think?)

strcpy(msg.name,"bob");

or

strncpy(msg.name,"bob",sizeof(msg.name));
