问题描述

Richard，你好，

我正在尝试在SimpleDate.cpp&中使用您的日期函数. Parseit.cpp

尝试编译它们-SimpleDate.cpp中的三个主要错误

我已经附上了给出错误的代码行.如果您有时间看一眼，它将非常有帮助.

祝一切顺利

肯


运算符int(){return atoi(TheData);};

错误消息:

Hi Richard,

I''m trying to use your date functions in SimpleDate.cpp & Parseit.cpp

tried compile them - three main errors in SimpleDate.cpp

I''ve attached the lines of code which give the error. If you have some time to have a look it''ll be most helpful.

All the best
