Help saving additional data to file?

[gator6688]

I need to be able to save my additional data to my .dat file. The additional data is not part of the vector though. It is data I made after the vector. I have to save the finalGrade and letter grade to my file.Also, how can I save my letter grade to my file when I didn't actually name it that?

	Grade(string nm, double exOne, double exTwo, double hw, double final){setGrade(nm, exOne, exTwo, hw, final);};
	void setGrade(string nm, double exOne, double exTwo, double hw, double final){name=nm; examOne=exOne; examTwo=exTwo; homework=hw; finalExam=final;};
	string getName(){return name;};

I'm a little confused by what you mean "you didn't actually name it that". Can you not use the name you named it as?
[code=cpp]
outFile.open(fi lename.c_str()) ;
[/code]

You are trying to open the file for reading and writing, am I correct? It looks like you do not specify that in the open() function, using ios::in | ios::out after the filename.
