can this be in programming language C, thanks

Suppose you want to implement a simple library called numbers that will export a lot of functions to find out about numbers (e.g.. positive, negative, even, odd etc.) For the time being, suppose your library exports only two functions int even (int x) and int positive(int x) . These functions will return 1 if the given number is even and positive, respectively; otherwise return 0. Define an interface named numbers.h exporting the above two functions (give the boilerplate lines (#ifnde, #de fine, #endif)) and implement numbers.c /**numbers.h */ /*numbers.c / What is the purpose of the boilerplate lines in the above file? Now suppose you want to implement an application that asks user to first enter a number. It then prints " this is a positiveegative even/odd number" on the screen. Implement myapp.c using the functions from the above library. myapp.c ****/ * myapp.c cont'd ***/
