所有的语言(大部分)都是平等的。

在很长一段时间里，我认为语言的选择对开发过程的难度和项目成功的潜力并没有太大的影响。这绝对不是真的。

为工作选择正确的语言与任何其他单个项目决策一样重要/关键。

没有bug的软件是可能的。

如果每一行都计算条件，如果你写这样的代码:

Dim a as Boolean = True
If a Then
    Console.WriteLine("1")
    a = False
    Console.WriteLine("2")
Else
    Console.WriteLine("3")
End If

那么输出将是:

1
3

:

for (int i = 0; i < myObj.variable; i = i + 1)

优化为:

int j = myObj.variable; 
for (int i = 0; i < j; i = i + 1)

哇，当我意识到它们每次都在运行时，我停止在j的地方放入函数调用!

原因:

for (int i = 0; i < myObj.variable; i = i + 1){ 
    if (function_argument == NULL){ 
        myObj.variable++; 
    } else { 
        printf("%d", myObj.variable);
    }
}

并不等同于:

int j = myObj.variable;
for (int i = 0; i < j; i = i + 1){ 
    if (function_argument == NULL){ 
        myObj.variable++; 
    } else { 
        printf("%d", myObj.variable);
    }
}

任意的例子，但是您可以看到优化将如何改变执行。

. net结构体(c#和VB.NET)是引用类型，就像类一样。

我是在。net 1.0出现之前或之后的某个时刻“收到”这条智慧的(我不知道从哪里来的，它可能完全从我的脑海中冒出来，就像雅典娜从宙斯的额头上冒出来一样)，并一直保存着它，直到大约4个月前Jon Skeet对这个概念进行了消除。

感谢乔恩。

附注:与编程无关，但我也相信(直到5分钟前)“阿波罗从宙斯的额头上长成了一个完整的阿波罗”。

我很早就开始学习编程了。那时我14岁左右。我有各种疯狂的想法，但不要问我准确的时间，因为那是很久以前的事了。

Ok, so, I believed for a while that if you use the term synchronize in Java, then Java solves this nasting synchronizing thing for you I believed for at least half a year, likely more, that static typing would improve performance. I believed that freeing something would return memory back to the OS. I believed that malloc calls boil down to checking if there is enough free space on the OS, so malloc would be inexpensive. I thought a long while that Java was built with all the benefits and flaws of the other languages in mind, into a "perfect blend" that would take the best properties of the other languages and reject the mistakes. I vastly overestimated the number of cases where LinkedLists outperform ArrayLists. I thought that NP-hardness was a proof that no INSTANCE could be solved efficiently, which is trivially false, for a while. I thought that finding the best flight-plan on travel agency web sites would take so long because of the "Travelling Salesman Problem", as I proudly chuckled to my relatives (when I was small, alright?!)

还能想出更多。不知道我坚持了多久。对不起。

PS: 啊，好吧，这个被清除得并不慢，但我看到新手时不时地这样做，所以我想你可能会感兴趣:我还认为要存储不确定数量的东西，你需要为每个东西声明一个新变量。所以我要创建变量a1 a2 a3…，而不是使用一个变量a，我将它声明为一个向量。
