是否可以输入某种变量并在C中同时将其与另一个变量进行比较？

Question

I was wondering if there was possibly a way where one could scan a variable and then compare it all in the same line (same time). 我想知道是否可能有一种方法可以扫描一个变量，然后将它们全部在同一行（同一时间）进行比较。

So far I tried this: 到目前为止我试过这个：

if(strcmp((scanf("create.%s",comp)),comp)==0)          //Please do not mind any missed parentheses or something like that...

I know ^that doesn't work because I've tried it and it ended up with an error... 我知道^那不起作用，因为我已经尝试过了，结果却出现了错误......

So how would one achieve such a task? 那么如何实现这样的任务呢？ Or is it impossible? 还是不可能？

It didn't work since scanf returns length, not char pointer 它没有工作，因为scanf返回长度，而不是char指针
The fact that you write it in the same line have nothing to do with the execution time, you might as well separate it into two parts. 你在同一行写它的事实与执行时间无关，你可以将它分成两部分。
If you really really want to do that (and I see no reason to), you may do the following: 如果你真的想这样做（我没有理由），你可以做以下事情：
```
 char *superScanfWithString(const char *format, char * str) { scanf(format,str); return str; } ... if(strcmp((superScanfWithString("create.%s",comp)),comp)==0) 
```
