参数：-------------------------------------------------------------------------------------------------------------

dest  ：Pointer to destination.c       ：Character to set.count：Number of characters.说明：-------------------------------------------------------------------------------------------------------------Sets the first count characters of
dest to the character c. （置dest的前count个值为c）依赖头文件：----------------------------------------------------------------------------------------------------memset
