题目：取一个整数a从右端开始的4～7位。 程序分析：可以这样考虑： (1)先使a右移4位。 (2)设置一个低4位全为1,其余全为0的数。可用~(~0<<4) (3)将上面二者进行&运算。 2.程序源代码：(Topic: take an integer a from the right end of the four to seven began. Program analysis: it can be to consider: (1) to make a move to the right four. (2) sets a low four total for the 1, all the rest for 0 of the number. Can be used to (~ 0 < < 4) (3) will above the difference and operations. 2. The source code:)
