不好意思，还想问学长几个问题~~1。what is i after the following for loop? for (int i=0;i (more...)

我的一点想法1. the three parts of for loop part I: initialization part II: governing condition (for the loop to continue) part III: post condition, i.e. what's going to happen after each loop however, ++i requires that increase i by 1 before entering a loop, this conflict with part III definition. 2. because the way float(double) numbers are represented in computer, u will find some floating point computing "wrong": 0.5 + 0.2 /= 0.7. 3. if (even==true) in C, you can write if (var = somevalue), which will assign somevalue to var and return true, but in java, this is not allowed. 4. even = number%2==0 even = (number%2==0) sequence of actions taken by computer: (1) computer number%2 (2) compare the previous result and 0 and return comparision result as a boolean value (3) assign the boolean value to even. 其实每个问题都有想对应的理论（或者说术语）来解释的， 不过我一时间都想不起来是什么， 希望你大概明白吧。 如有纰漏，敬请各位更正。
