C++学习组合类时编的程序通不过编译，到底是那里有错？
一下为编译过程中出现的错误：
C:\Documents and Settings\cc\My Documents\1020_1.cpp In constructor `People::People(Date)':
64 C:\Documents and Settings\cc\My Documents\1020_1.cpp no match for call to `(Date) (Date&)'
C:\Documents and Settings\cc\My Documents\200610113055_焦圆_1020_1.cpp In member function `void People::Input()':
91 C:\Documents and Settings\cc\My Documents\200610113055_焦圆_1020_1.cpp no match for call to `(Date) (Date&)'
以下为源程序：

按java 中函数名和变量名用小写，如果是两个单词联合起来的第一个单词小写，第二个单词的第一个字母大写，不然看名字分不清楚
