How to get input from multiple files?
Hi,
I'm creating a program that needs to read in a filename from stdin, open it, and do some processing, then repeat the process until the user enters "quit." I get the first file processed fine, but it crashes when I try to open the second file. Actually, the program enter the if (! inFile) section of code even if the second filename is correct and the file exists. I think it's because the filestream is bad at the end of the first file. There must be some way to reuse the same file handle. Here is what I've got:
Code:
int main()
{
ifstream inFile;
string inFilename;
Maze m1;
cout << "Enter filename with stored maze or \"quit\" to end: ";
cin >> inFilename;
inFile.open(inFilename.c_str());
while(inFilename != "quit")
{
// make sure input file was opened properly
if (! inFile)
{
cout << "Error opening file \"" << inFilename.c_str() << "\"\nProgram will now exit.\n";
return 1;
}
m1.readMaze(inFile);
m1.printMaze();
inFile.close();
cout << "Enter filename with stored maze or \"quit\" to end: ";
cin >> inFilename;
inFile.open(inFilename.c_str());
}
return 0;
}
Any idea what I've got wrong? Thanks!
