In C++, Write value function fullName that accepts three string parameters as input: first name, middle name, and last name. If the middle name is not provided in the function call, use a default value of "Q". The function returns a string that combines the three name parts into one. Show two calls to fullName, one with three arguments and one with two arguments, and the value returned from each call.
