C++ Topological Sort/ Acyclic check

**Topological Sort and Acyclic check ** **Using appropriate, user-friendly prompts have the user input a set of tasks into an array of strings, e.g.,** **1. Paint walls 2. Install electrical wiring 3. Lay foundation 4. Do roofing 5. Put up drywall 6. Install plumbing 7. Frame house ? ? ? ? ? ? ? ? etc.** After the user has entered the tasks, your program should then have the user specify (using user-friendly prompts) an order relation on pairs of tasks, e.g., 3 1 (indicates that Task 3 must precede Task 1) 7 5 (indicates that Task 7 must precede Task 5) 5 1 (indicates that Task 5 must precede Task 1) etc. Your program then applies the topological sorting operation to output the tasks in topological order. Note that your program may not be able to find a topological order for a directed graph which contains cycles. So, your program should output either a topological order (if successful) or the message that the directed graph is not acyclic.
