以下声明通过编译检查:
int arr[3];
vector<int[3]> vec; // ok !!
当试图vec实际使用时,
vec.push_back(arr);
它导致许多错误,如:
/usr/include/c++/4.6/ext/new_allocator.h:108:9: error: ISO C++ forbids initialization in array new [-fpermissive]
/usr/include/c++/4.6/bits/vector.tcc:314:4: error: invalid array assignment
/usr/include/c++/4.6/ext/new_allocator.h:118:30: error: request for member ‘~int [3]’ in ‘* __p’, which is of non-class type ‘int [3]’
另外,vec也不push_back()是int*.
这到底出了什么问题？是否在C++ 11中解决了这个问题？
