emmmm 第三题有要求用循环重复输入 输入非正值的时候循环结束这样
呃......，还是那句话书不在身边，到时候拿书看一下，可能写的时候忘记看题的要求了
兄弟，第九题我还是没看懂
要是有注释就好了
难理解的地方才加有注释，简单点的按照练习意思理解就好
第四题计算height_feet，用到了强制转换int，但是我去掉了这个，结果输出是一样的，怎么回事啊
因为上面的代码里面我将height_feet定义为int，所以就算你将强制类型转换int去掉，当将最后计算出来的结果赋值给height_feet的时候还是会被截断为int的
210行到213行：题目是输入华氏度，输出华氏度、摄氏度、开氏度。
输出的字符串名字错了，Fahrenheit_temp改成Celsius_temp比较好吧，毕竟定义了temperature就代表了华氏度
我的妈呀最后一题怎样都看不懂有点崩溃
do while 还没学呢。。。。
Hi 楼主，我感觉第9题函数里的公式好像写错了
书上说的是：
摄氏温度=5.0/9.0*（华氏温度-32.0）
开氏温度=摄氏温度+273.16
还有就是变量命名有点混淆
Fahrenheit是华氏温度，Celsius是摄氏温度
麻烦楼主有时间看一下~
编译器打不出来啊
