那是因為怕久而久之,
積了一堆goto後,
會令程式有bug(s).

现在讲究结构化设计 一般不建议用goto来跳

GOTO is a concept of JUMP transit from assembly language (ASM). In C/C++, there is enough method to replace GOTO, such as IF-ELSE, SWITCH, WHILE... .

謝謝  給了我很大的幫忙喔  版主  推推

goto is not recommended in C++ due to its poor performance, but you can still use it for error handlings.

i use a software 'press',it need use many goto,i write once then not want edit again

GOOD!!感謝大大無私奉獻!!

Try not to use GOTO .  It is a bad coding style in C++ and make the code much difficult to read and fix in the future.

goto虽然很方便，但对于大的程序来说，程序可读性差

GOTO会使程序结构过于混乱
