已经在这个程序上工作了一段时间了。(遇到了一些问题,在这里问了几次。)虽然遇到了另一个问题!该程序两次询问我的帐户类型。无法弄清楚为什么或如何解决它。任何帮助表示赞赏,谢谢!

theirAccType = accType();
...
split = pricePerCheck(accType(), checksWritten());
//                    ^^^^^^^^^

你是accType第二次打电话了。您应该传入用于在第一行保存初始调用的变量。

split = pricePerCheck(theirAccType, checksWritten());
//                    ^^^^^^^^^^^^

当您调用时,pricePerCheck()您传递调用的结果accType()而不是theirAccType: 您存储了第一次调用的结果,但您正在进行第二次调用。C++ 不会记住函数调用的结果。

顺便说一句,您想编译具有更高警告级别的代码!您的代码中有许多致命问题:

  1. personalCalc()被声明为返回int但不返回任何东西(该函数没有被调用,即你的问题,显然不是SSCCE
  2. 该函数commericalCalc()使用未初始化变量 ( written) 的值。它似乎也不好命名。

帐户类型的请求在accType()函数中进行。您在这段代码中调用了该函数两次:

 displayInstructions();
  theirAccType = accType();
  accountNumb = readAccNumb();
  split = pricePerCheck(accType(), checksWritten());

accType()被调用以将值分配给theirAccType,并再次作为 的参数pricePerCheck()

你可能需要

  split = pricePerCheck(theirAccType, checksWritten());
