C/C++ 中从来没有定义过void main( ) 。C++ 之父Bjarne Stroustrup 在他的主页上的 technical FAQ 中明确地写着:
The definition
void main() { /* ... */ }
is not and never has been C++, nor has it even been C. See the ISO C++ standard 3.6.1[2] or the ISO C standard 5.1.2.2.1. A conforming implementation accepts
int main() { /* ... */ }
and
int main(int argc, char* argv[]) { /* ... */ }

最好在main函数的最后加上return 语句，这是一个好习惯。
