Output result:

字符"A"输出的各种形式:
%c    = A
%hhd  = 65
%-10c = A
%10c  =          A
%010c = 000000000A

字符串"ABCD"输出的各种形式:
%s      = ABCD
%-10s   = ABCD
%10s    =       ABCD
%010s   = 000000ABCD
%.2s    = AB
%5.2s   =    AB
%05.2s  = 000AB
%-05.2s = AB
%*.*s   =   ABC  //参数5,3;

指针输出的三种形式:
%p      = 00057D14
%-10p   = 00057D14
%10p    =   00057D14
