我得到的错误是:变量或字段 PrintSummaryReport 声明为 void

然后我还得到:在函数 voidPrintSummaryReport 中...无法将 FILE 转换为 const car 作为 int printf(const char*...) 的参数用于以下几行

printf(reportFile,REPORTLINEFORMAT1,fullName,payrate,regHours,gross,fedtax,
        ssitax,netpay);
    printf(reportFile,REPORTLINEFORMAT2,ovtHours,statetax,deferred);

Answer 1

在 do block 中，有以下语句:

void PrintSummaryReport(reportFile,fullName,regHours,ovtHours,payrate,gross,deferred,
        ft,st,ssit,netpay)

删除 void 关键字，因为您正在那里调用该函数。

然后，关于 printf 中的错误，我认为您不能将 printf 与 FILE* 一起使用，如错误所述。 fprintf 应该没问题。您可以查看printf等详细信息 here 。请注意，这是针对 Linux 的，但它也应该适用于在 Windows 上使用 C。
