我是一个c++萌新，自学了一个月多点，大一的时候上过一点c语言，我现在想用c++来判断一个身份证号时候合法，因为我很垃圾嘛，所以我想让大家尽情的指出我的不足和错误，我写的这个也是不全的，先用生日来判断合法但是我这个不知道我的错误在哪，基本上是自己瞎写的

using namespace std;
void happy(int month[2], int a, int day[2], int year[4], int carry1) {
	a = month[0] * 10 + month[1]; if (month[0] < 10 && month[1] < 3)
		 {
		switch (a) {
		case 1:if (day[0] < 4 || day[0] == 3 && day[1] < 2) { cout << "合法"; }
			  else { cout << "不合法"; }break;
		case 2:if (carry1 % 4 == 0 && carry1 % 100 != 0 || carry1 % 400 == 0) {
			if (day[0] < 3 || day[0] == 2 && day[1] < 9) { cout << "合法"; }
			else { cout << "不合法"; }
		}
			  else { cout << "不合法"; }
			  if (day[0] < 3 || day[0] == 2 && day[1] < 8) { cout << "合法"; }
			  else { cout << "不合法"; }break;
		case 3:if (day[0] < 4 || day[0] == 3 && day[1] < 2) { cout << "合法"; }
			  else { cout << "不合法"; }break;
		case 4:if (day[0] < 4 || day[0] == 3 && day[1] < 1) { cout << "合法"; }
			  else { cout << "不合法"; }break;
		case 5:if (day[0] < 4 || day[0] == 3 && day[1] < 2) { cout << "合法"; }
			  else { cout << "不合法"; }break;
		case 6:if (day[0] < 4 || day[0] == 3 && day[1] < 1) { cout << "合法"; }
			  else { cout << "不合法"; }break;

		case 9:if (day[0] < 4 || day[0] == 3 && day[1] < 1) { cout << "合法"; }
			  else { cout << "不合法"; }break;
		case 10:if (day[0] < 4 || day[0] == 3 && day[1] < 2) { cout << "合法"; }
