是否可以在C中使用scanf + regex获得空行？

Question

I know that fgets is more appropriate for this, but would it be possible to use scanf to read a line that has only \\n (maybe by using a regex expression?) ?

EDIT: the formqt suggester by @dasblinkenlight works to get the \\n, however, it has undesirable side effects. For example :

#include <stdio.h>

int main(){
 char c[80];
 for (int n = 0; n<10; n++){
  scanf("%1[\n]", c);
  printf("%d %s\n", n, c);
 }
 return 0;
}

If I just input enter , it actually works as expected (catching the new line and printing it). However, if I input another character, it it goes through the loop until the end without waiting for any other input.

Just use fgets() . If the returned string is empty, stop. If it is not empty, use sscanf() to parse it.
