Use programming c for this exercise. in this exercise, you will write a point structure that represents a space in two-dimensional space. this point should have both x and y elds ( use these exact names). you will also write three functions for dealing with points; freadpoint, manhattandistance, and euclideandistance. freadpoint should take in a file handle and return a point; it should not do any prompting. each point will be a line in the le, with the x and y coordinates separated by spaces. the manhattandistance function will take two points and compute the manhattan distance (city block distance) between them, which is the distance that you would travel if you are restricted to walking parallel to either the x or y axes. likewise, the euclideandistance function will take two points and compute the euclidean distance (straight-line distance) between them. neither function prints anything; they simply return a value. your main function will prompt the user to enter two points and then display the manhattan and euclidean distances. you should call each of your functions (using stdio as a parameter to freadpoint) to do so.
