    debug assertion failed!

    can anyone tell me why i am getting error while runtime

    Code:
    Section defGeometry::formSection( Side Section1,Section Section2,int N1,int N2,int N4,int NumberOfPoints )
    {defFile defG;
    //std::vector Sections FinalSection;
    int NoOfPoints,i,j,k;
    N1=2;
    N2=2;
    j=0;
    k=0;
    NoOfPoints=2*N1;
    struct Section defGeomSecTemp;
    struct point x;
    
    double defGeompt[3];
    
    for(i=0;i<N4;i++)
    {
    	for(j=NumberOfPoints-N2;j>=NumberOfPoints-N2;j++)
    	{
    		x.pt[0]=Section1.Sections[N4].Points[NumberOfPoints-N2].pt[0];
    		
    
    	}
    }		
    
    return  Section3;
    };

    Perhaps it has to do with a vector subscript being out of range.

    You have a vector with X elements, and you are trying to "use" elements beyond X.

    Again, you should check your subscripts. I don't know what the actual cause of your problem is, because that code doesn't make any sense. I'm hoping and wishing that what you've posted is not, in fact, your actual code, because otherwise you've got a lot of things missing. In future, post actual code.

    Code:
    Section defGeometry::formSection( Side Section1,Section Section2,int N1,int N2,int N4,int NumberOfPoints )
    {
    	defFile defG;
    	//std::vector Sections FinalSection;
    	int NoOfPoints,i,j,k;
    	N1=2;
    	N2=2;
    	j=0;
    	k=0;
    	NoOfPoints=2*N1;
    	struct Section defGeomSecTemp;
    	struct point x;
    
    	double defGeompt[3];
    
    	for(i=0;i<N4;i++)
    	{
    		for(j=NumberOfPoints-N2;j>=NumberOfPoints-N2;j++)
    		{
    			x.pt[0]=Section1.Sections[N4].Points[NumberOfPoints-N2].pt[0];
    		}
    	}
    
    	return  Section3;
    };
    Try indenting better next time. { are reserved for the {, so don't put any code there.
    Since a function is a block, indent all code inside it at least once.
    And typing "struct" before the struct name is not required in C++, so you can drop it.
