    easiest way of writing all the contents of

    I have a class definition as the following

    Code:
    class SimulationTiming
    {
    public:
    	LARGE_INTEGER freq;
    	LARGE_INTEGER startTime;
    	LARGE_INTEGER stopTime;
    
    	vector<float>	locateNeedleTime;
    	vector<float>	setConstraintAngleTime;
    	vector<float>	checkSurfaceTime;
    	vector<float>	addNodeTime;
    	vector<float>	computeThresholdsTime;
    	vector<float>	resolveInterceptTime;
    	vector<float>	mmult2time;
    	vector<float>	updateLCSXYZtime;
    	vector<float>	BCCtime;
    	vector<float>	ConstraintDispXYZtime;
    	vector<float>	ConstriantDispXZtime;
    	vector<float>	UpdateLCSXZtime;
    	vector<float>	solvesystemtime;
    	vector<float>	projectiontime;
    	vector<float>	computeNNDistanceTime;
    	vector<float>	projectforcestime;
    	vector<float>	integrateforcestime;
    	vector<float>	findallnodestime;
    	vector<float>	solveneedlespringtime;
    	vector<float>	initvartime;
    
    public:
    	SimulationTiming(void);
    	void startTimer(void);
    	void stopTimer(vector<float> *list);
    	~SimulationTiming(void);
    };
    I'm trying to write all the vector contents into its own text file. However, I'm not sure what's the easiest way of doing so. I have looked into fwrite, fprintf, and fstream classes, but not sure about the easiest way to go in terms of dumping the contents for a vector into a file. An example would be much appreciated. Thanks.

    Code:
    	vector<float>	locateNeedleTime;
    	vector<float>	setConstraintAngleTime;
    	vector<float>	checkSurfaceTime;
    	vector<float>	addNodeTime;
    	vector<float>	computeThresholdsTime;
    	vector<float>	resolveInterceptTime;
    	vector<float>	mmult2time;
    	vector<float>	updateLCSXYZtime;
    	vector<float>	BCCtime;
    	vector<float>	ConstraintDispXYZtime;
    	vector<float>	ConstriantDispXZtime;
    	vector<float>	UpdateLCSXZtime;
    	vector<float>	solvesystemtime;
    	vector<float>	projectiontime;
    	vector<float>	computeNNDistanceTime;
    	vector<float>	projectforcestime;
    	vector<float>	integrateforcestime;
    	vector<float>	findallnodestime;
    	vector<float>	solveneedlespringtime;
    	vector<float>	initvartime;
    Are these all updated at the same time?
    If so, I would suggest you make a struct
    Code:
    struct data   // Use a better name!
    {
    	float	locateNeedleTime;
    	float	setConstraintAngleTime;
    ...
    	float	initvartime;
    };
           vector<data> dataVector;
    Once you have that, you could define a operator<< for a data element, that outputs all the elemets of one struct to a output stream. That is the common way to do this sort of thing.

    It's not trivial, but not too bad either.

    The vector members are not updated at the same time. I found something on Google with more appropriate search terms to come up with something like C++ : Outputting a vector to a file, and other problems. - Topic Powered by Eve For Enterprise for writing the contents of a vector to a file. Thanks for your help though.
