Question

程序可以正常工作并执行所有操作，直到我到达该函数计算“年度销售额”和“季度平均值”的部分为止。我不确定问题是在功能中还是在信息显示中。

“年销售额和平均季度销售额”显示为-6.27744e + 66

我觉得我缺少明显的东西。

    double firstQSales;                                                     // First Quarterly Sales
    double sndQSales;                                                       // Second Quarterly Sales
    double thirdQSales;                                                     // Third Quarterly Sales
