C++ language please and dont forget the flowchart. Thank you so much

8. (12.5 pts) Convert temperature: Create a flowchart. Then write, compile, and test a C++ program that uses a switch structure where the user is prompted to enter a temperature and a unit (c, C, f, or F). If the temperature is entered in degrees Fahrenheit it should be converted to degrees Celsius. If the temperature is entered in degrees Celsius it should be converted to Fahrenheit. Hint: Read the temperature as a double and the unit as a char. Example: Input: 35.2c Output: 35.2 degrees C=95.4 degrees F - Use the format specified earlier (initial block of comments with TCC logo, name, description, etc.) - Give clear instructions so that the user knows what to enter. - The output should display the result in both degrees C and degrees F as real numbers. - The program should print an error message if an invalid unit is entered. - Test the program for the 7 inputs shown below. 0c 100C 25.2c 32f 212F 65.4F - Any number followed by an invalid letter - Turn in a printout of the program and printouts of the 7 test cases
