Windows中的时间./a.out等价物 [英] Time ./a.out equivalent in Windows
问题描述
在Windows中是否存在等价的方法
''时间./a.out''
来衡量执行时间一个节目？
最好的问候，

我们不知道。好吧，这里的一些人可能碰巧知道，但是这个
不是要问的地方，因为你的问题真的不是关于C
编程语言。
尝试使用comp.os.ms-windows。*或microsoft。*新闻组之一。

We don''t know. Well, some people here might happen to know, but this
isn''t the place to ask, since your question really isn''t about the C
programming language.
Try one of the comp.os.ms-windows.* or microsoft.* newsgroups.

我把下面的C程序放在一起模糊地工作，但你可能会得到关于如何正确地做到这一点的想法。 （我以前从未在C
中使用过命令参数。）

int t;
int i，m;
char ** p;
if（n< = 1）
{if（n == 1）printf（" Usage：％s filename \\\
"，* cmds）;
return EXIT_FAILURE;
};
++ cmds; / *第一个感兴趣的参数，应该是exe名称* /
/ *必须检查所有参数组合适合cmdstring（你可以忽略这个如果
不发布你的代码！）* /
m = 0;
p = cmds;
for（i = 2; i< = n; ++ i）m + =（strlen（* p ++）+ 1）;
if（m> sizeof（cmdstring））返回EXIT_FAILURE;
/ *全部麻烦系统去分隔params，现在我们需要
再次将它们加在一起，空格在* /
/ *之间提示：如果你可以使用Winmain（ ）相反，参数已经联合起来
* /
strcpy（cmdstring，* cmds）;
for（i = 3; i< = n; ++ i）
{strcat（cmdstring，""）;
strcat（cmdstring，*（+ + cmds）） ;
};
printf（" Executing％s ... \ n"，cmdstring）;
t = clock（）;
system（cmdstring）;
t = clock（） - t;
printf（执行时间：％d毫秒） ，t）;
返回EXIT_SUCCESS;
}
I put together the C program below which vaguely works, but you might get
ideas on how to do it properly. (I''ve never used command parameters in C
before).
