第一次发表海报。我正在编写一个计算联邦所得税的计划。用户输入状态代码（1,2,3,4）以表示归档状态。我要为此编写一个函数，以获得税收收入，计算税额并显示结果。我还使用两个一维数组来计算税率和申请状态。我到目前为止所写的内容已经发布。任何帮助表示赞赏。 为什么我会收到错误？如何修复函数和数组？

答案 0 :(得分：1)
您发布的错误正在发生，因为编译器无法找到main。发生这种情况是因为您打开了比关闭时更多的花括号。此外，我不会过多地谈论你的编码风格，但这里还有一些可怕的错误：
std:int getStatusCode()
这里不需要std:，无论应该做什么。
std:string
这应该是std :: string，它是命名空间，而不是goto标签或其他东西。您甚至在开头使用了using namespace std;。
由于您没有关闭所有花括号，因此可能会发生其余错误。另请注意，您提供了
的声明void displayResults();
float getTaxIncome();
但您没有提供实施。
这也没有任何意义，我也不知道你在那里做什么：
cin >> statusCode = 9;
第46行还有一个没有分号的返回。
while (statusCode < 1 || (statusCode > 4 && statusCode != 9));
这个while循环没有正文...
for (int i = 0; i < size(filingStatus); i++;)
对于数组也没有size函数，只需使用4，它是一个简单的数组，你知道它的大小。在i ++之后不应该有分号。
搜索更多错误没有任何意义，从一个简单的项目开始并学习C ++的基础知识。这段代码只是一团糟，不应该在stackoverflow上发布。
