被零除导致不确定的行为，没有C语言结构，可以做任何事情。***的办法是零摆在首位，以不分，通过检查分母。

Division by zero leads to undefined behavior, there is no C language construct that can do anything about it. Your best bet is to not divide by zero in the first place, by checking the denominator.

如果你想钓（注意，C有没有例外）这个错误，这将取决于你的编译器和操作系统，你还没有上市。顺便说一句， _control87 只有做浮点运算，并没有做整数运算。

If you want to "catch" (note, C has no exceptions) this error, it will be dependent on your compiler and OS, which you haven't listed. By the way, _control87 has only to do with floating-point operations, and nothing to do with integer operations.
