In C Programming

- Show how you could implement the strdup() function yourself. This function will take one parameter (a string) and allocate and return a duplicate of the string. For full credit, be sure to check that the input string and the result of the allocation are not NULL, and return NULL if there is a problem.

- Assume that struct point is declared to contain two integers, x and y. Write a function which will dynamically allocate a new point, taking its x and y values as parameters and returning a pointer to the allocated object. Check the result of the allocation.

-Write a section of code which will allow the user to input 3 integer values on a single line, and report whether any of them divide evenly into any of the other ones.
