debug error using struct

I tried to execute the following code...

#include "def_struct.c"
int main()
{
float Max_Eval;
int level =0;
result=PSO(level, Max_Eval);
}
where pso is a structure
struct position PSO(int level, float Max_Eval)
{
int add_option=1;
int already;
.........
}

and struct position is defined in def_struct.c
struct position {struct vector p;struct f f;};
struct position PSO(int level, float Max_Eval);

When I debug the code,the program throws an exception while trying to call pso.Can anyone help me in this regard.

What does your call stack look like? What line in "PSO" is throwing the exception?

Viggy

The call stack looks like

Tribes1.exe!PSO(int level=0, float Max_Eval=40000.000) Line 490 C

The exception is thrown at the very first line in struct position PSO .

Could you post your whole struct ? yours doesn't look correctly-defined and that counts.

I have attached the struct code as an attachment

The function is declared before calling the function as
struct vector {double x[Max_DD];int size;};
struct f {double f[Max_f];int size;};
struct position {struct vector p;struct f f;};
struct position PSO(int level, float Max_Eval);

Kindly help me.

I think Mattrang was incorrect about struct definition, the implementation and and function declarations for the most part look really ill-formed, sorry I am currently under bad weather. Would you mind posting some other implementation parts of the work you are laying your hands on ? I think it wouldn't be a good idea for us to only guess where the mistake lies with such a little piece of information.

Post your whole project - not just portions.

Include the DSW so that we can rebuild it just like you have done.

I have attached the whole project.The main file is main.c and the def_struct.c contains all the declarations.The text files functions.txt and problems.txt will feed the necessary parameters for running the program.
thanx n regards
