Confusion With Structs

Alright,

I'm getting errors and it's confusing me on how to declare and pass a struct.

If you pass a struct, you need to tell your program that it's a struct, so

void posmath (POS sales, int *intCount, double *total, double *stotal){

should be

void posmath (struct POS sales, int *intCount, double *total, double *stotal){

Also, because you're working in C++, you need to declare what namespace you use

alright got it, thanks.i did declare my namespace in my custom stdheader.h where I imported everything.xboxrulz
