在C中帮助这个程序 [英] Help in this programm in C
问题描述
嗨。我在一段时间之前就开始学习程序语言C.我是在试图制作关于一个非常简单的卖店的程序。这个程序
没有任何编译问题，但当我运行它时，我面对其他一些我无法纠正的b $ b ploblems。如果有人拿一个
看看我会很感激我的程序是为了帮助我。我多次尝试找出
，我的错误在哪里，但我没办法处理。
我已经做了一些评论到程序，以使其更容易
容易。
关于我在程序中的写作风格的任何建议是
可接受。
请帮帮我!!!

trying to make a programm about a very simple "sell shop".This programm
hasn''t got any compile problem but when i run it i face some other
ploblems which i can not correct.I would appreciated if someone take a
look at my programm so as to help me.I tried many times to find out
where my mistakes are but i didn''t manage something.
I have made some comments due to the programm so as to make it more
easy to as.
Any recommendations about my writing style in the programm are
acceptable.

编码风格？是的，尝试使用缩进方式如下：
缩进-npro -kr -i8 -ts8 -sob -l80 -ss -ncs
（un * x实用程序）缩进）
Coding style? yes, try to use indent in way such this one:
indent -npro -kr -i8 -ts8 -sob -l80 -ss -ncs
(un*x utility for indentation)

这很容易出错。如果我输入char 15，它就会崩溃。
另一件事，打开警告，它会告诉你，这很糟糕。
titlos尚未指针，所以scanf（"％s"，titlos）;是正确的，

Another thing, turn on warnings, it would tell you, it''s bad.
titlos is pointer yet, so scanf("%s", titlos); is correct,
