VC 中这种语法合法吗？

[antinet]

#include <iostream>
#include <iostream>
#include <cmath>
using namespace std;
struct date{
unsigned int year:6;
unsigned int month:4;
unsigned int day:5;
unsigned int hour:5;
unsigned int minute:6;
unsigned int second:6;
date(){}
date(int y, int mon, int d, int h, int min, int s){
year = y;
month = mon;
day = d;
hour = h;
minute = min;
second = s;
}

上述struct中int year:6这样的语法结构在VC6中合法吗？在哪里合法？C#吗？哪位高人解释一下上述程序：结构定义的语法，date(){}后没有分号，接着date(int y....){...}是什么意图？请解释清楚，学习了

这有点像pascal的语法，delphi和C#都继承了pascal的特点

应该还是C++，C#的包含头文件是using，这里是include

等人编译,语法上来说没问题.

using namespace std;
struct date{
unsigned int year:6; //这是位域
unsigned int month:4;
unsigned int day:5;
unsigned int hour:5;
unsigned int minute:6;
unsigned int second:6;
date(){}
date(int y, int mon, int d, int h, int min, int s){
year = y;
month = mon;
day = d;
hour = h;
minute = min;
second = s;
} //除了这里少了个;外，没看到什么问题

[Quote=引用 5 楼 hairetz 的回复:]
using namespace std;

unsigned int month:4;
unsigned int day:5;

unsigned int second:6;
date(){}

year = y;
month = mon;
day = d;

应该是少了};吧
