3.19 LAB: Seasons In C++ Write a program that takes a date as input and outputs the date's season. The input is a string to represent the month and an int to represent the day. Ex: If the input is: April 11 the output is: Spring In addition, check if the string and int are valid (an actual month and day). Ex: If the input is: Blue 65 the output is: Invalid The dates for each season are: Spring: March 20 - June 20 Summer: June 21 - September 21 Autumn: September 22 - December 20 Winter: December 21 - March 19
