错误预期';'在'endl'之前

Question

我在任务中遇到了标题问题。请任何人尽快帮助我。

/*
    member function of studentInfo class; store the value of all data members in 
    the text file named "record.txt", on separate lines in the text file.
*/
void storeFile()
{
   cout<< "All the data members are stored in file." << endl;
   ofstream outFile;
   const char* outputFileName = "record.txt";
   outFile.open(outputFileName, ios::out);
   if(!outFile)
   {
       cout<< "\nUnable to open the file." << outputFileName << endl;
   }
   else
   {
       outFile vuID;
       outFile endl;
       outFile campusID;
       outFile endl;
       outFile studentName;
       outFile endl;
       outFile fatherName;
   }
}

Answer 1

outFile endl;

这不好。 endl是std命名空间中的标识符。你想用这个做什么？这没有意义。

Answer 2

您需要将变量放入outputFile e.g。

outFile << vuID;

Answer 3

outFile vuID

表单不正确，与

相同

utFile endl;

应该是

outFile << vuID

和

outFile << endl;
