I've got the class member:

LineND::LineND(double a ...) { coefficients.push_back(a); va_list arguments; va_start(arguments, a); double argValue; do { argValue = va_arg(arguments, double); coefficients.push_back(argValue); }while(argValue != NULL); // THIS IS A PROBLEM POINT! va_end(arguments); } 

I don't know how many arguments will be used. I need to take each argument and put it into the vector called coefficients. How should I do that? I understand, that the statement while(argValue != NULL) is not correct in this case. I can't use for example this signature

LineND::LineND(int numArgs, double a ...) 

to change the condition like this

while(argValue != numArgs); 

The point is I can't change the signature of the method. Need to resolve this problem another way.
