cin >> sex;
cout << "录入身份证:";
cin >> ID[17];
ID[17] = '';
cout << "录入出生日期:";
birthday.enteringbirthday();
}
void People::show(){
cout << "编号:" << number;
cout << "性别:" << sex;
cout << "身份证:" << ID;
birthday.showbirthday();
}
int main(){
People x;
x.entering();
x.show();
return 0;
}

解决方案

身份证18位加上需要19才够。

解决方案二：

身份证数组应该19位，输入时需要数组名即可，不需要单独加字符串结束标志。

char ID[19];
 cin >> ID;

解决方案三：

不是id无法输入数值
