Write two functions having the same name Add and both take two parameters. When called from main, they will print I have been called n times where n is the number of calls, they have received from main, and will return the sum of arguments passed. Note: Keep taking input until the user enters -1. Example Output: Add(12,12); Sum = 24, I have been called 1 time Add(45,1254); Sum = 1299, I have been called 2 times Add(45.89,12.45); Sum = 58.34, I have been called 1 time Add(1,15); Sum = 16, I have been called 3 times (This was dummy output; you are supposed to take input from the user and add them until the user enters -1)
