是VS不标准，not是C++的关键字，和class、if这些是同级的。但在C里，not是个宏，好像是include在stdlib.h里。
std::ostream& operator<<(std::ostream& out, Node n)也能使编译器闭嘴 可见他的理由不是很充分，但是他的建议值得你去实行！当一个函数中的参数在调用过程中不改变其值，就尽量用 const type& 来替换 type ，注意这里的type最好是自定义类型，因为内置类型int double用第二种更快！第一种少了...
这样不行,因为cin >> i;将调用标准库中的istream& operator>>(istream &in, int &t); template <typename T> istream& operator>>(istream &in, T &t) { ... } 别人写的一个Check Input class: class ChkInput { public: ChkInput(istream &in) : m_in(in) {} template <typename T> ChkIn...
Like the run-time functionsprintf, theostrstreamclass supports output to in-memory strings. To create a string in memory using I/O stream formatting, construct an object of classostrstream. Becauseostrstreamobjects are write-only, your program must access the resulting string through a pointer toch...
IIRC的C++流必须与C I/O"构造"同步(如果出于兼容性的原因)。我相信你可以通过关闭同步来加快速度(如果以后你不得不停止做printf之类的事情的话)。 @borgleader:ostream同步到什么C"构造"(它是一个文件输出流,而不是std::out),为什么它比C fwrite慢?
template<classElem,classTr>basic_istream<Elem, Tr>&operator>>(basic_istream<Elem, Tr>&Istr,Elem*str); extracts up toN - 1elements and stores them in the array starting atstr. IfIstr.widthis greater than zero,NisIstr.width; otherwise, it's the size of the largest array ofElemthat can...

我对C ++相当陌生,我不知道如何运行它。当然,在询问之前我做了一些研究,但是我想到的方法并没有产生预期的结果:lambdarookies-MacBook:02-the-set-class lambdarookie$ ./02-the-set-class 1 2 3 3 4 5 s = {2} // Expected: s = {1, 2, 3} t = {3, 4, 5} Run...
VS2015CTP 编译成功。用的VC6.0？更换编译器吧！
