This can be necessary

diresu(makeITwork)
"return bSuccess" returns integer value of bSuccess. For a 64bits computer, there are ~2^64 possible or returns. Later use of == may cause unexpected results.
"return bSuccess?True:False" returns finite value of either True or False. Later use of == is safe anywhere. if-then-else will generate the same code after compiler done its work.
A complex line of good-looking C code normally generate the same code after compile as several line of simple verbose ugly codes. Single liner is good for text books, tests and interviews. Verbose code may do good to projects - when you have to put enough lines of comments for each line you wrote 5 years ago for knowledge transfer, verbose codes is definitely preferred.

  • 工作学习 / 学科技术讨论 / 又没有人见过比这个吐血的程序：一段把字符串转换成大写的程序，竟然有人用穷举法if string='a' then string='A'来实现？ -yesiam(party time); 2008-11-10 {316} (#4830018@0)
    最近在debug公司一套运行了10几年舍不得升级的老系统，发现一个程序老是运行不出来。花了九牛二虎之力才发现一个2000年做的程序，很简单的upcase()函数，一个2000年的programmer竟然写了几十条if then把所有可能的输入一个个转换。因为最近有了新的数据，if then就做不出来了。大概这就是传说中IT bubble的时候在书店给人抓进来的programmer

    • Look at it positively. Because of this or those errors, many programmers have work chance. Otherwise … :) -deep_blue(BLUE); 2008-11-11 (#4834107@0)
    • 这肯定是按行数挣钱的。王小波诗云：一个和尚独自归，关门闭户掩柴扉。另外很奇怪：为什么新数据if then就做不出来？26个字母没列全？ -holdon(again); 2008-11-11 (#4834518@0)
      • 可能现在要支持多国语言了，楼主不是按行拿钱，不想写汇编了 -c1xwy(洪兴罩俺去战斗); 2008-11-11 (#4834613@0)
        • 2000年的程序我怀疑哪个upcase能支持多国语言？所以新数据该不工作还是不工作啊。 -holdon(again); 2008-11-11 (#4834615@0)
      • 不是每个字母，而是每个可能出现的数据，打个比方，每个员工的人名，换成大写，这样每进来一个新员工，就要多加一行if then....然后还有人说这样容易维护，还跨平台。看样子野鸡IT学校真的养活了不少人。 -yesiam(party time); 2008-11-12 (#4837225@0)
    • 其实,有什么好嘲笑的呢?又不是错了.就算你对了,也就是雕虫小技而已. -iwantcar_majia(iwantcar); 2008-11-11 (#4834637@0)

      • 能招进来那样的人，你们公司也就是那种找人免费做几个月然后给reference货色而已 -yesiam(party time); 2008-11-12 (#4837213@0)
        • haha. 我公司的实习生的工资和学历都有可能比你高.省省吧. -iwantcar_majia(iwantcar); 2008-11-22 (#4865647@0)
