使用上区别是:1、using namespace std;只需要放在程序最前面,用于限定如cin、cout等。2、using std::使用时,也是放在程序最前面,如:using std::cin、using std::cout、using std::endl。3、std::std::cin、std::cout、std::endl,每次使用都要在前面加上std::。#C / C++ ...

cin.get(c); gets the next character in thegetbuffer and updates the buffer pointer inThreadA. However, if the next instruction inThreadAis anothergetcall, thelibClibrary does not guarantee to return the next character in the sequence. It is not guaranteed because, for example,ThreadBmay have ...

A common use of nonlocal names is the use of thecinandcoutstreams within a template. Few programmers really want to pass the stream as a template parameter, so they refer to a global variable. However,cinandcoutmust have the same definition everywhere. ...
