Question

我似乎无法在我的代码中发现问题是我生病还是失明我不确定。我得到的错误是：

unresolved external symbol"struct MonthlyBudget_cdecl actual(void)" (?actual@@YA?AUMonthlyBudget@@XZ) referenced in function_main.

任何帮助都将不胜感激。

再次感谢您的帮助！我知道代码非常混乱，有更好的方法可以做到这一点，但对于我的生活，我现在想不出任何与我的流感有关的事。

Answer 1

从actual（）和所有提及中删除（）。修正了程序。

未解析的外部符号“struct MonthlyBudget_cdecl actual（void）”
