Bellow code is for 'init array element in strcut'
.name, why it is not .name[10] = "Bob", because it is like char arrary_name = {...} instead of char array_name[#] = {...}(updated) after reading the comments/answers, now I know this format is 'Designated initialization' in C99
typedef struct
{
char name[10];
char age;
}Man;
void main()
{
Man man1 =
{
.name = "Bob", // why not .name[10] = "Bob",
.age = 18
};
printf("%s\n", man1.name); // "Bob"
printf("%d\n", man1.age); // 18
}
I have doubt about .name, why it is not .name[10] = "Bob"
It is unclear to me why you think it should be .name[10] = "Bob", so I will try to answer it in a few different ways.
Because the declaration char name[10]; does not create a member called "name[10]"; it creates a member called "name", and the type of that member is char[].
Because the type of "Bob" is char[], so you can only use it to initialize another char[], you cannot use it to initialize a char.
Because the type of name is char[], therefore the type of name[10] is char, so you cannot initialize it with anything but another char.
Because name[10] should not be initialized with anything anyway, because it is one position past the end of the array. (Valid indexes are 0 to 9, this does not include 10.)
