推荐答案

编译器可以告诉您有关代码的一些信息.一旦感到高兴，它的真正含义就是语法确定.该程序本身仍然很糟糕.

A compiler could tell you a couple of things about your code. And once it is happy, all it really means is the syntax is OK; the program itself could still be utter crap.

用于(int i; 0< i< 128; i ++)
...
for(int i; 128< i< 256; i ++}

for (int i; 0< i<128;i++)
...
for (int i; 128< i<256;i++}

基本上是相同的错误，请问是1还是2?

:)

Basically the same mistake, does that count for 1 or for 2?

:)

哇.从6下降到5.您需要更加具体.

Wow. Down from 6 to 5. You need to be more specific.

我从不知道我们在CodeProject上有没有编译器就可以发现错误"的竞赛:)

I never knew that we have ''Find error without Compiler'' competition on CodeProject :)
