对于一个似乎应该"正常工作"的程序,我遇到了一个奇怪的错误.

Question

我向你们展示了我正在为我的大学编程课程所做的一个项目.我还有一些方法可以完全达到我的任务要求,但是我已经得到了程序的基本草案,没有错误(据说)并且它似乎运行...但是它突然把我踢进了Xcode的调试器并给出了我:

Thread 1: EXC_BAD_ACCESS(code=2, address=0x7fff95c1e5f5)

这是命令行输出,直到它把我踢出去:

    -----------------------
    Quarterly_sales_taxator
    -----------------------


    How many company divisions will we be dealing with?  2


    Am I correct in assuming that there are 4 sales quarters?    yes



    Please enter the sales Company Division #1 brought in for Sales Quarter #1   20
    (lldb)

这是我的代码:

有些灵魂请告诉我我做错了什么？

Answer 1

    {   quarterly_sales_form[COMPANY_DIVISIONS] = new double [SALES_QUARTERS];  }

在这一行,COMPANY_DIVISIONS应该是count.
