c語言習題

巢狀結構概念。
程式碼:

#include  
#include 
typedef struct time{/*定義全域結構，並定義型態*/
 int hour;
 int minutes;
 double second;
} times;
typedef struct date{/*定義全域結構，並定義型態*/
 int year;
 int month;
 int day;
 times s;//呼叫結構 
} data;
void display(data );/*函數*/
int main(void){
 data now = {2016,8,31,{11,47,36.46}};
 display(now);
 
 system("pause");
 return 0;
}

void display(data a){
 printf("%2d/%2d/%d  %2d:%2d:%.2f",a.month,a.day,a.year,a.s.hour,a.s.minutes,a.s.second);
}
