c++ code

Write a function that accept integer values for day, month and year and return them in valid format. If day is above 30, then it convert day to 30. If month is above 12 then it convert month to 12. Similarly if day or month is below 1 then it converts them to 1. Finally it ensures that the years are between 2000 and 2014. If all inputs are valid then it returns true else it returns false. Write a program that prompts user to input day, month and year. The program then validates them using the function written above and displays validate if all the input are valid. Otherwise the program displays invalid and the corrected values of input returned by the function
