Reading/Writing C++ File Question

MrMario (8)
Hello,

I am wanting to read a data file that is placed in my project file where the driver.cpp, function.cpp and function.h are located.

I want to the user create an output file name. How can I do this and where should it be placed?
Also I put my other question below some of this code.

Thanks for the help! :)

	////Problems reading or getting file; Closes program
	//if (total == -99)

	//}

	AnalyzeFile(flowData, total, highIndex, lowIndex);
	Write = WriteFile();

	cout << "\n";

	return 0;
}

bool WriteFile()

	//Checking to see if I can open the results text file

	}
	//printing the results in a text file .txt
		output <<"C++ Data Created By: "
		 <<"\nThanks for using the C++ Data Reader";

	output.close();

	return true;
}


I'm also wanting to know where I should put these two lines at.

	cout << "\nLowest flow was " << flowData[rLow];
	cout << "\nAcre-feed per month in " << flowData[rLow] << endl;




I don't want to show the results to the user in the cmd, but want to show the results in a text file the user created.

Function.h

What do you mean? So you want the user to read a file, then create a new file name? And why are you asking where the file should be placed? That's up to you, or the user if you allow that kind of functionality.

Read about file streams.

What I am wanting is the program to open the file that placed in the program file where the driver and function folders are. Then once the program does the calculations, I would ask for a new file name of the users choice where it would be placed in the same place where the other file is.

But I sorted it all out this afternoon.

=> Solved
