因为你骗了编译器。为什么要神奇地弄清楚

你想要的这种未定义的行为的几种可能解释中的哪一种?

Because you''re lying to the compiler. Why should it magically figure out
which of the several possible interpretations of this undefined
behaviour you want?

1.没有适当的缩进(停止使用Google发布;

获得真正的NG客户端)。

2.我不得忘记包括STDIO.H - 荷马(好吧,不是真的)。​​

3.听说过强迫吗?


问候,

1. No proper indentation (stop using Google to post;
get a real NG client).
2. "I MUST NOT FORGET TO INCLUDE STDIO.H" - Homer (well, not really).
3. Ever heard of coercion?

Jonathan.

你在printf()中使用了错误的转换说明符。 "%d"期望

一个int参数。使用%f相反。

返回0;
}

the code:

{
float i=6.10203;
printf("%d",i);
You''re using the wrong conversion specifier in printf(). "%d" expects
an int argument. Use "%f" instead.
return 0;
}
is giving the o/p zero. why??????



使用错误的转换说明符会导致不可预测的结果。


Using the wrong conversion specifier leads to unpredictable results.
