    Passing structs as parameters

    Hey guys, I have a struct which has its elements used in a function and then another function is called which doesn't require the structs elements but then this function then calls a third function which does require them. At the moment i have the first function passing the structs object to the second function and then from the second to the third function even though the second function doesn't require the structs object data.

    Was this the best way to do this or is there another way? Thanks.

    Use a pointer to the struct. When working with a struct through a pointer, don't forget to use the "->" operator for dereferencing and working with the elements.

    It sounds like you are using the wrong program structure. main() should be the air traffic controller. main() should call the first function and send it the necessary arguments, and the first function should then return to main(). Then main() should call the second function and send it the necessary arguments, and then the second function should return to main(), etc.

    Yes. This assumes that there is a reason the first function calls the second function which calls the third function. You say that "the second function doesn't require the structs object data", but if the second function has to call the third function, and the third function requires it, then the second function requires it.

    Chances are you could design your functions better, but without doing that your approach is correct.
