Thread: Classes: adding a new variable produces errors

Hi all,
I have a class inside a program and at the moment it works fine. But when I add one more variable to it - then I run into the errors in the program - it actually runs, but all the other variables have some random number. I guess I run into some memory issues.
So here is my class:

Code:

class plasma_class
{
public:
	float PeakDensity;
	short DensityProfileX;
	short DensityProfileY;
	short NumberOfSpecies;
	double RoughnessAmplitude;
	double RoughnessPeriod;
	//double FrontPreplasmaLength;
	//double RearPreplasmaLength;

	struct specie_class
	{
		int ParticlesPerCellX;
		int ParticlesPerCellY;
		int Charge;
		double Mass;
		double ReciprocalMass;
		int NumberOfParticles;
		int CellsPlasmaX;
		int CellsPlasmaY;
		double StartX;
		double EndX;
		double StartY;
		double EndY;
		double PeakCharge;

	struct particle_class
		{
		//public:	
			double x;
			double y;
			double p_x;
			double p_y;
			double p_z;
			//double ExParticle;
			//double EyParticle;
			//double BzParticle;
			double q;
			short InsideVolumeFlag;
		};

		std::vector<particle_class> particle;

		
	};

	std::vector<specie_class> specie;

	plasma_class(const char *, simulation_class simulation);

	void move(simulation_class simulation, fields_class &fields, int TimeStep);
	

};

Problems start when I uncomment for example FrontPreplasmaLength. Could anybody help me understand all this stuff and resolve the problem

Thanks in advance

Cheers, Mats you saved the dummy once again
