1、　　编写一个计算机程序用来计算一个文件的16位效验和。最快速的方法是用一个32位的整数来存放这个和。记住要处理进位（例如，超过16位的那些位），把它们加到效验和中。-1, the preparation of a computer program used to calculate a file of well-tested and 16. The fastest way is to use a 32-bit integer to store this and. Remember to deal with binary (for example, those more than 16-bit), add them and in well-tested.
