先来看一段代码 #include using namespace std; int main(){ char* str[4][5]={ {"00","01","02","03","04"}, {"10","11","12","13","14"}, {"20","21","22","23","24"}, {"30","31","32","33","34"}, }; cou

这里复习下预编译头的知识，都知道预编译头是为了加快编译的速度，如果没有预编译头，那么每次在生成obj的时候，都要先把源码编译成字节码，而对于变动很小的文件来说，这样做是没有必要的，可能生成一份固定的字节码文件，以后有地方要用的时候，添加进去即可。有人说编译器不是本身就有时间戳的功能吗，没有修改过的文件本来就不会进行编译，可是这是两件事情，由于cpp对于每个文件是独立编译的，A.cpp文件被多个地方

#include using namespace std; class TestProperty{ public: int mp1; int mp2; int mp3; }; void testProperty(){ coutmp1) coutmp2) coutmp3) coutmp1 } 以上几个表达式能正常输出吗，如果能，输出的又是什么呢？
