+# Calling and Returning From Functions
 
 Calling functions, passing parameters to them and receiving back return values is basic to using `C` and and `C++`. Calling methods (which are functions connected to classes) is similar but with enough differences to warrant its own discussion to be provided later in the chapter on [structs](../struct/structs.md).

 Up to 8 parameters can be passed directly via registers. Each parameter can be up to the size of an address, long or double (8 bytes). If you need to pass more than 8 parameters or you need to pass parameters which are larger than 8 bytes or are `structs`, you would use a different technique described later.
