对于cin，则是istream流类的对象，其重载了>>运算符，用法与cout大致相同。技巧应用 把设计的cout对象命名的myout，myout对象所属的类为MyOutstream。要做的就是为MyOutstream类重载一系列不同类型的operator 定义的myout已经初具形态，可以工作了。程序中的注释指出两处要特别注意的：即是operator 还记得那个有点...
C语言中的 stdout 是一个定义在的宏（macro），它展开到一个 FILE* （“指向 FILE 的指针”）类型的表达式（不一定是常量），这个表达式指向一个与标准输出流（standard output stream）相关连的 FILE 对象。释义 只是方便操作输出，比如传给一个函数等等。这时函数的输出就不是输出到文件，而是传进来的stdout文件...
