我是一个刚开始学习c++的菜鸟，编了一个小程序
调试通过了，但运行的时候却崩溃了
那位大哥帮我看一下
谢谢！

[diaoni]

int j = rand ()*5; //j=?????
if (_shopping.GetConsumer()[j].GetFlag() != false) //_shopping.GetConsumer()[j]数组越界

好象下面也有这样的错误。

[xuzheng318]

有可能数组越界，或者内存泄漏，溢出 什么的，编译是看不出来得！
要debug跟踪！

[cainiao0823]

恩

我用debug跟踪是错误提符显示在Consummer 类的 bool GetFlag () {return _flag;}
private:
bool _flag;

附近,但我看不出错在那里

[cainiao0823]

to::o1n(小毛子)
把Goods merchandise [5] = {Goods("Apple", 2.0),Goods("orange",1.8),Goods("pig",16.2),
Goods("Cake",6.4),Goods("pear",1.4)};的定义放在int Process::Run ()前面
刚才我打错了

[cainiao0823]

谢谢大家

找到错误了，结贴
