无论c是什么。
'' \\ 0''和0都是常量主表达式
类型为int且值为零。

It doesn''t matter what c is.
''\0'' and 0 are both constant primary expressions
of type int and value zero.

呃，实际上，在C中，char是一个8位整数（不是所有）。
''\ 0''的ASCII值是0.So c =''\ 0''等于c = 0.在许多程序中，我们使用char代替<当整数很小时，
of int。
Er,in fact,in C, a char is an 8-bit integer(not all).The ASCII value of
''\0'' is 0.So c=''\0'' equals to c=0 .In many programs,we use char instead
of int when the integer is small.
