Qt编译报错unknown type name 'namespace" pro文件中有重复的文件声明。
这是.c文件中引用c++标准的原因,可将文件后缀修改为.cpp,使用C++编译 4.出现unknown type name ‘namespace’ 这是c编译c++的问题, c中没有namespace关键子,可将文件后缀修改为.cpp,使用C++编译,或者去掉该关键字 5.出现iostream no such file or directory 在.h中调用了#include <iostream> , 此头文件是cp...

If names reflect types rather than functionality, it becomes hard to change the types used to provide that functionality. Also, if the type of a variable is changed, code using it will have to be modified. Minimize unintentional conversions.
