For example, functions that temporarily place a null character into the middle of a string are detected at compile time, if passed a pointer to a string that cannot be so modified. 6.6.5 volatile Means Exact Semantics So far, the examples have all used const because it's conceptually ...
这里补充说明一下,我就是分享我的思路,我也写了我是菜鸟,我今年刚考完研,也没参加比赛,我会继续写也只是因为有人问。我之前比了三次美赛,一个H、一个M、一个S,另外有一篇一作SCI。我基本也是单核带队打,我也就是给做不完的或者不会同学提供点帮助,你要是很会,不要看我的思路,自己去实现,可以用我的...
