In the entry function to complete the initialization of the ServiceMain, the more accurate is to initialize a service_table_entry structure array, this structure records all the services contained in the name of the service and the entry point function, below is a service_ Examples of table_entry:Service_table_entry service_table_entry[] ={{"Myftpd", Ftpdmain},{"Myhttpd"

Problem 29:divide two integers
does not use division, multiplication, and remainder operations to complete two-digit division, and returns Max_int when the value overflows.
Solution: The first idea, directly with dividend cycle minus divisor, each reduction of the result is greater than 0, the result plus 1, less than 0 o'clock cycle end. The solution is fine, but the complexity is too high, and when you remove a small number with a large number,
