Consider the following fragment of code which is meant to add two together two xy points, and answer the two questions below: struct point { int x: int y }: struct point* add_points(struct point*p1, struct point*p2) { struct point result: result.x = p1 rightarrow x + p2 rightarrow x: result.y = p1 rightarrow y + p2 rightarrow y: return&result: } Most of the time function will appear to work fine, but then later there will be an issue with the result point's data changing unexpectly. a) What is the problem? b) How it can be fixed
