如何在 C 驱动器中为 C++ 保存 output 文件

Question

Ive been able to succesfully create a file, rename it, and then save it, however I need help in trying to save it in the C:\ drive but no luck.

string filename, newfile;

ifstream wordInFile(filename); 

cout << "Please enter filename to open" << endl;
cin >> filename;


cout << "Please enter the name for your new file" << endl;
cin >> newfile;

ofstream tempFile(newfile);       //Creating and opening a temporary file to store the needed words




wordInFile.close(); //Close the input file

tempFile.close();    //Close the temp output file

Answer 1

Try switching the order:

string filename, newfile;
cout << "Please enter filename to open" << endl;
cin >> filename;

ifstream wordInFile(filename); 

In general, you want to have valid content in your variables before you use them.
