结果如下:
DSPLY size of Str1 = 10
DSPLY len of Str1 = 10
DSPLY size of P1 = 8
DSPLY len of Str1 = 15
DSPLY size of Str1 = 10
DSPLY len of Str1 = 10
DSPLY size of P1 = 8
DSPLY len of Str1 = 15
DSPLY size of S1 = 15
DSPLY len of S1 = 15
DSPLY size of date1= 10
DSPLY len of date1= 10
DSPLY size of int1 = 2
DSPLY len of int1 = 5
%len取的就是定义变量时的长度
%Size取的是变量实际占用内存的长度,byte为单位
