i have tried hard but dont know wy im getting this error , error comes in line 8

class CPop 
{
CBSVector<CTour> pop;
CBSVector<double> probability;
int popsize;
double TotalFitness;
CTour Elite;
**CTspGAParams GAParameters;**
}

error C2059: syntax error : 'constant'
error C2238: unexpected token(s) preceding ';'

Nothing jumps out at me from the code you've posted, but if I've missed something obvious, someone else will surely point it out. Failing that, and because the actual error could be prior to the source line reporting it, could you post the content of tour.h also?

i was tinking the same but i guess tis is not te issue bcz when i try composint tspgaparam object in some other class i get same error on line where i declare object as data member, plz smone figure this out, i dont know what the problem is with this line! either i m mising some header or what .

What are the ** used for? I'm new to coding so I am unfamiliar with that. Also, maybe in order to complete your class CPop, you need to put a semi-colon after the } on line 9. Sometimes that helps the program understand that there is no actual problem with your code.

I think lines 1..9 are just a cut-down version of the actual code in the header file, which is contained in lines 17..68, and which does terminate with a semicolon. But tspga can perhaps clarify.

bob you are right, it is cut down version, and zvjezdan ** is used to just make line prominent** in post it is not related to c++ syntax and for those who read replies because they are facing similar errors i would like to tell i have resolved my issue and the matter was some missing header files, proper initialization of member variables in constructor of tspgaparam class and just replacing this "CTspGAParams GAParameters" by "CTspGAParams gaParameters", i was able to resolve this matter... this means avoid naming your object variables with capitals or atleast first alphabet must be lower case.
