First-chance exception in SA.exe: 0xC0000005: Access Violation.

下面是调试器的相关截图：

我调试在微软我的编译程序时的Visual C++ 6.0得到如下。

这编译和在VS2008上运行良好。除非是VC6编译器错误，否则不要认为问题出现在代码中。 – drby 2009-03-04 09:28:36

您能否提供发生碰撞时使用的输入值？ – 2009-03-04 10:06:56

你确定你没有编译一个模块和另一个编译器吗？做一个干净的，看看错误消失。也看起来你没有检查输入范围（如果T_current = 0，T_Initial> 0和T_abs <0可能会很糟糕）。 – johnny 2009-03-04 18:36:32

您发布的代码甚至不会编译：

1）

cin >> Go.Write;

在SimAnneal类中没有这样的变量。

2）

Go.SA(Go.Write)

你SA方法不接受任何参数。

另一件事是，为什么不直接在VC++ 6.0中以调试模式运行项目？截图上的VS显然是200 * X *。

根据截图，你崩溃就行了：

cout << "Quadratic Function" << endl 
    << "Solving method: Simulated Annealing" << endl;

这并不多大意义，除非你的输出流以某种方式肢解。在发生崩溃之前，您是否尝试过观看控制台？

它看起来并不像你在代码中做的任何事情都是致命的，我可以看到，你是否试过删除代码行？

a = S_order [i];
b = S_order [i + 1];
距离+ = CityArray [a] [b]; < ---这看起来很可疑。当i = 14，B = 15 ...显然超出范围...... 我的2美分

但我小于15 - 1，这是小于14.因此，我不能高于13. – 2009-03-04 05:07:13

试试这个：

但我认为答案是什么别人说 - 的距离=行

for (int i = 0; i < 15; i++) 
{ 
    S_trial [i] = S_order [i]; 
} 

// .... 
for (int i = 0; i <15; i++) 
{ 
    S_order [i] = i; 
}

两个循环都过高。他们更改为14，而不是15

可以随时把try {}赶上（...）{}周围代码块和编译/ EHA

找出问题所在
