Tocompile this program, you must add#includedirectives for both theiostreamandstringlibraries andmust issueusingdeclarations for all the names used from the library:string,cin, cout, andendl. 对于上例,编译时必须加上#include来标示iostream和string标准库,以及给出用到的所有标准库中的名字(如string,cin...
这里的string::npos就是一个长度参数,表示直到字符串的结束,配合idx+1表示,string的剩余部分。 #include <iostream>#include<limits>#include<string>usingnamespacestd;intmain() {stringfilename ="test.cpp"; cout<<"filename :"<< filename <<endl; size_t idx= filename.find('.');//as a return ...

These include string manipulation, memory allocation, C-style input/output calls, and others. MSVCP*.DLL is the corresponding C++ library. msvcrt.dll是MSVC4.2到6.0版本之间的标准C库,而msvcp*.dll是对应的C++标准库(和上文相同)。 With Version 14.0, most of the C/C++ runtime was moved into a ...
