这个都不知道是那里错了.

gcc test.cpp -o test
应该用：
g++ test.cpp -o test

gcc is a compiler for C, supporting (with the -traditional flag) Kernighan and Ritchie`s dialect, (with the -ansi flag) the ANSI dialect and (by default) itsown somewhat enhanced dialect.
g++ and c++ are (identical as far as I can see) compilers for C++.
