论述*P++等价于（*p）++还是等价于*（p++）的问题，为了验证这个问题，编写了下面的小程序（vc++6.0编译环境），作为验证-Paper* P++ Is equivalent to (* p)++ Or equivalent to* (p++) Problems, in order to verify this issue, prepared the following small program (vc++ 6.0 compiler environment ), as a validation
SHOW FULL COLUMNS FROM `jrk_downrecords` [ RunTime:0.001407s ]
SELECT `a`.`aid`,`a`.`title`,`a`.`create_time`,`m`.`username` FROM `jrk_downrecords` `a` INNER JOIN `jrk_member` `m` ON `a`.`uid`=`m`.`id` WHERE `a`.`status` = 1 GROUP BY `a`.`aid` ORDER BY `a`.`create_time` DESC LIMIT 10 [ RunTime:0.081590s ]
SHOW FULL COLUMNS FROM `jrk_tagrecords` [ RunTime:0.000942s ]
SELECT * FROM `jrk_tagrecords` WHERE `status` = 1 ORDER BY `num` DESC LIMIT 20 [ RunTime:0.002313s ]
SHOW FULL COLUMNS FROM `jrk_member` [ RunTime:0.001237s ]
SELECT `id`,`username`,`userhead`,`usertime` FROM `jrk_member` WHERE `status` = 1 ORDER BY `usertime` DESC LIMIT 10 [ RunTime:0.005922s ]
SHOW FULL COLUMNS FROM `jrk_searchrecords` [ RunTime:0.001333s ]

SELECT aid,title,count(aid) as c FROM `jrk_downrecords` GROUP BY `aid` ORDER BY `c` DESC LIMIT 10 [ RunTime:0.016642s ]
SHOW FULL COLUMNS FROM `jrk_articles` [ RunTime:0.001226s ]
UPDATE `jrk_articles` SET `hits` = 2 WHERE `id` = 61920 [ RunTime:0.027732s ]
