2. C 中的联盟:联合是一种用户定义的数据类型,允许在同一内存位置存储异构元素。联合的大小是联合中最大元素的大小。下面是工会的生动表现。 工会声明: union name { datatype element; datatype element; }; 数组和联合的区别: ARRAYUNION 相同数据类型的元素的集合。异构数据类型元素的集合。 数组可以是一维或...

The VARIANT C type is basically a gigantic union; its definition can be found at bit.ly/2fMc4Bu. Just like for the BSTR C type, ATL offers a convenient C++ wrapper around the raw C VARIANT type: the ATL::CComVariant class. In C++ code, it’s simpler and safer to handle variants ...
Here, we are going to learn how to declare byte array and initialise array with decimal, octal and hexadecimal numbers in C language.

如果offset是正数且小于length,则返回数组会从offset开始;如果offset大于length,则不操作,直接返回。如果offset是负数,则offset = num_in+offset,如果num_in+offset == 0,则将offset设为0。 length 如果length小于0,那么会将length转为num_in - offset + length;否则,如果offset+length > array_count,则length ...
