Question

Which of the following is a properly defined structure?

(a) struct {int a;}

(b) struct a_struct {int a;}

(c) struct a_struct int a;

(d) struct a_struct {int a;};

Answer 1

Correct option is (d) struct a_struct {int a;};

Explanation: option struct {int a;} is not correct because name of structure and ;(after declaration) are missing. In option struct a_struct {int a;} ; is missing. In option struct a_struct int a; {} are missing.
