从身份证号获取信息 Apare_xzc

身份证号信息获取系统 Apare_xzc

---

by xzc （大一写的）

---

系统功能：

  输入一个身份证号，判断身份证号的合法性，返回从身份证号码中获取的信息。

---

效果预览：

---

错误输入类型：

1. 身份证号代表的出生年月日不合法

2. 身份证号校验位不正确

---

用到的知识点：

1. sscanf()函数：从字符串中读取信息

2. 控制台输出控制字符颜色：

HANDLE hc = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleTextAttribute(hc,F|B);

3. 控制台清屏：

system("CLS");

4. 身份证号所代表的信息：

• 身份证倒数第二位，奇数为男，偶数为女
• 身份证号最后一位是校验位。

sign = (str[0]*7 + str[1]*9 + str[2]*10 + str[3]*5 + str[4]*8 + str[5]*4 + str[6]*2 + 
        str[7]*1 + str[8]*6 + str[9]*3 + str[10]*7 + str[11]*9+ str[12]*10+str[13]*5 + 
		str[14]*8+ str[15]*4+ str[16]*2
	   ) % 11;

• 身份证号前六位，代表完整的地区信息
• 身份证号码前两位，代表省或自治区、特别行政区
