小编use*_*850的帖子

我正在将一大块代码从gcc移植到Visual Studio 2013.以下代码示例在gcc 4.4上工作正常(!),但在VS2013上编译begin()并end()失败:

错误C2440:'':无法从'unsigned char*'转换为'std :: _ Vector_const_iterator >>'

class foo {
    unsigned char* value;
    int length;

    std::vector<unsigned char>::const_iterator begin();
    std::vector<unsigned char>::const_iterator end();
};

std::vector<unsigned char>::const_iterator foo::begin() {
    return std::vector<unsigned char>::const_iterator(value);
}

std::vector<unsigned char>::const_iterator foo::end() {
    return std::vector<unsigned char>::const_iterator(value + length);
}

鉴于我不想重写整个事物,是否有可行的方法来创建这些const_iterators？
