Struct student_st {char c; int score; const char * name;}; static void show_student (struct student_st * stu) {printf ("c = % c, score = % d, name = % s \ n ", stu-> c, stu-> score, stu-> name);} int main (void) {// method 1: initialize struct student_st s1 = {'A', 91, "Alan"}; show_student (& s1); // method 2: Specify initialization, the order of the members is variable. This mode is usually used in Linux kernel struct student_st s2 = {. name = "YunYun ",. c = 'B ',. score = 92 ,}; show_student (& s2); // method 3: Specify initialization. The member sequence can be variable. struct student_st s3 = {c: 'C', score: 93, name: "Wood" ,}; show_student (& s3); return 0 ;}

If you want to initializeStruct Array, You can use the {}, {}, {} method, as shown in figure

Struct student_st stus [2] = {{. c = 'D ',. score = 94,/* can only initialize some members */},{. c = 'D ',. score = 94 ,. name = "Xxx "},};
