C - Help printing a member of a returned Struct


Your struct busRoute should be defined in BusRoute.h, not BusRoute.c, if you want to use it in main.c. And you do want to use it in main.c, if your getBusRouteInfo() function returns one. Without main.c being able to see this definition, it doesn't know that struct busRoute even has a member named busRouteNumber, let alone how to get at it, so that's why compilation fails.

Your other option is to define a function like getBusRouteInfoRouteNumber(2), which will return the appropriate member indirectly. That way, main.c doesn't need to know anything about the actual struct busRoute.

print member of struct of a vector
Boost Adaptor adapts ranges, not single iterators. Similarily, the boost::copy algorithm expects two arguments, where the first one is a range, and the second an output iterator. Having said that, the correct syntax for extracting a single data member from a range, and copying it to an output iterator is: boost::copy(pntVec | boost::adaptors::transformed(bind(&pnt::_type, _1)) , std

Access struct member from pointer
As said by barak manos, your problem lies in init. C pass parameters by value so let's imagine : you set a pointer to pile to NULL (pile *p = NULL;) you pass it to init (init(p);) in init you alloc a pile and affect is to the local copy of p on return from init, p is still NULL and you have a memory leak since you have no longer any pointer to the allocated pile That's the reason why you shoul

Compile Error, Member is not a member of a union | working with pointers/structs
line 74 was corrupted: instead of void convertStringToTime(char * strTime , TTime * Zeit) it had to be void convertStringToTime(char * strTime , TTime * lp). anything else seems to be fine. Will try to get the memory allocation done now and look at strtol() as an alternative solution.

Template Member function cannot see non-templated class member correctly
Check your default constructor, copy constructor, and any other custom constructors/move/operator functions you write/overload. Make sure these are doing what you think they are doing. Templated functions work just fine in non-templated classes. Data being inaccurate or missing is most likely a copy issue. Edit: As pmr mentions below... Obey the rule of five. That is definitely the main point.

Const struct assigned to struct
It is not the same. You are trying to assign const pointer to a non const pointer. Another words: trying to assign Mutable pointer to a constant StudentType to a non-const pointer. It does make sense to change something that is declared const to no-cont, meaning you could change a value of a constant. What you are trying to do is to copy one object to another using shallow copy. in order to do so
