发帖数: 2126 | 3 这个题目建议用红黑树做可能最快捷有效。红黑树每一次插入，删除都是log(k),求平
均值非常简单，就是根部的那个节点。所以总的计算量是O(nlog(k))。
以下是c/c++代码（需要修改数组，以便一个一个输入）。

发帖数: 334 | 5 这段程序读boa的配置文件boa.conf,找到端口号后改写新端口，例如
Port 80
# Listen: the Internet address to bind(2) to. If you leave it out,
# it takes the behavior before 0.93.17.2, which is to bind to all
# addresses (INADDR_ANY). You only get one "Listen" directive,
变成Port 8080

发帖数: 7227 | 6 i typed a lot in chinese but it's gone, :(
anyway, say i have a file has 3 lines,
1: i
2: love
3: coding
now i want to modify the 2nd line,
1: i
2: don't love
3: coding
i can use fgets to read each line, then use fputs to write all 3 lines back.
but it's a waste, can i just write the 2nd line pack ?
the issue is the length of 2nd line get changed.
any way to make it better ?
thanks so much ! |

我已经把put这个动词应该的用处说了
如果还是不理解的话
那就具体一个例子
map.put是最直观的
puts用来表达print给人感觉怪怪的
c这么做未必代表其正确
只能说不可避免的是所有东西都带有c的痕迹
不同的人会作出不同的选择
这就好像公孙大神说的，你要这么说，我们所有东西都可以归到c去

发帖数: 149 | 10 To build a shared object( .so file),I used following commond:
gcc -fPIC -shared -o output.so input.c
and foo( ) is a function defined in input.c
In order to call foo, I did following in calling process:
void * handle = dlopen("output.so",RTLD_LAZY);
if((error=dlerror())!=NULL){
fputs(error,stderr);
exit(1);
}
foo = dlsym(handle,"foo");
foo()...
However, I got result:
./output.so: undefined symbol: foo
I am pretty sure the problem is from the shared object output.so which was not |
