I saw some C code like this:
int check = 10:
switch(check) {
case 1...9: printf("It is 2 to 9");break;
case 10: printf("It is 10");break;
}
What does this case 1...9:
mean? Is it standard?

It's a GNU C extension called case range.

As noted in the document, you have to put spaces between the low and high value of the range.
case 1 ... 9:
statement;
is equivalent to:
case 1:
case 2:
case 3:
case 4:
case 5:
case 6:
case 7:
case 8:
case 9:
statement;
