vector::erase和iterator的問題

vector::erase後，原本的iterator會失效
所以在使用for-loop + erase要特別注意

help有指出,vector::erase會回傳一個有效的iterator


A random access iterator pointing to the new location of the element that followed the last element erased by the function call, which is the vector end if the operation erased the last element in the sequence.

std::vector values;
for (std::vector::iterator it = values.begin(); it != values.end(); )
{
    if (*it > 10)
    {
        it = values.erase(it);
    }
    else
    {
        ++it;
    }
}
