The discriminator type must be an integral type (short, long, long long, and so on, as well as char, boolean, or enumeraton).

识别名称类型必须是整数类型（short 、long 、 long long等，以及char 、boolean或 enumeraton ）。

For the types char and short, the compiler needs to reduce the size of the local variable to 8 or 16 bits after each assignment.

对于char和short类型，编译器在每次分配空间以后，都要将这种局部变量的尺寸减少到8位或16位。

Similarly, when a small integer (char, short, int) is passed into printf (3), it will be widened to 64-bits and the sign will be extended if appropriate.

类似地，当一个小整数（char、short、int）被传递给printf (3) 时，它会扩展成 64位的，符号会适当地进行扩展。

If those all fail, it looks for foo (short), foo (char), and foo (byte).

如果全部失败，它会查找foo (short)、foo (char)和foo (byte)。
