可以在C++中循环遍历数组结构

如果之前已经回答过，请提前道歉。没有找到任何内容（或者没有使用正确的搜索词）。无论如何，我想知道我的代码中有一个特定的部分是否可以通过循环来完成。我继续添加了下面的代码。我认为可能需要清理的两个部分是请求用户输入在各种预算类别上花费的金额。我曾计划使用for循环，但不知道如何将值分配给MonthlyBudget结构"currentMonthlyBBudget"的各个元素（即currentMonthlyBudget.housing、currentMonthleBudget.utilities等）。这对expenseCategories[]来说是有效的，但我可以找到如何（或者是否可能）为结构做这件事。如有任何协助，我们将不胜感激。提前谢谢。
