大于和小于switch语句C [英] Larger than and less than in switch statement C

问题描述

我正在尝试编写一个有很多比较的代码

I'm trying to write a code that has a lot of comparison

Write a program in "QUANT.C" which "quantifies" numbers.  Read an integer "x" and test it, producing the 
following output: 

x greater than or equal to 1000 print "hugely positive" 
x from 999 to 100 (including 100) print "very positive" 
x between 100 and 0 print "positive" 
x exactly 0 print "zero" 
x between 0 and -100 print "negative" 
x from -100 to -999 (including -100) print "very negative" 
x less than or equal to -1000 print "hugely negative" 

Thus -10 would print "negative", -100 "very negative" and 458 "very positive".

然后我尝试使用开关来解决它但是它不起作用，我是否必须使用if语句解决它或者有一个使用开关来解决它的方法？

then I tried to solve it using switch but it didn't work, do I have to solve it using if statement or there is a method to solve it using switch?

推荐答案

没有干净的方法用switch来解决这个问题，因为案例需要是整数类型。看看if-else if-else。

There is no clean way to solve this with switch, as cases need to be integral types. Have a look at if-else if-else.
