our C/C++ code (.cpp) and to link it to the CUDA object file (.obj). The syntax for declaring the function prototype is: type function-name (formal parameter type list.

call () provides a new value of this to the function/method. To provide this information to the compiler, we must use a function declaration statement (or, function prototype declaration). The call () allows for a function/method belonging to one object to be assigned and called for a different object. It means that lp is a function that takes 2 parameters, the first being curr and the second being, well, a list, which logically, may be either empty ( ) or contain at least one element ( (a::l) is a pattern for a list where a is at the head, and the rest of the list is l). Function prototypes are an extension to the optional declaration of C functions. Function Declaration The C++ compiler requires specific information related to all functions activated in the program.
