事实上class用于定义类,在模板引入c++后,最初定义模板的方法为:template<class T>,这里class关键字表明T是一个类型,后来为了避免class在这两个地方的使用可能给人带来混淆,所以引入了typename这个关键字,它的作用同class一样表明后面的符号为一个类型,这样在定义模板的时候可以使用下面的方式了: template<typename T>...

每个C++/C程序通常分为两个文件。一个文件用于保存程序的声明(declaration),称为头文件。另一个文件用于保存程序的实现(implementation),称为定义(definition)文件。 C++/C程序的头文件以“.h”为后缀,C程序的定义文件以“.c”为后缀,C++程序的定义文件通常以“.cpp”为后缀(也有一些系统以“.cc”或“.cxx”为...
