Write a C++ program that will ask the user to input his/her full name. Then, ask for four test scores. The program should then calculate the average of the four scores. If the average is 90 or higher, the program should display the message: "Congratulations FULL NAME, you have an excellent score!". If the average is less than 90 but over 70, the program should display the message: "FULL NAME, you are passing the class". Otherwise, if the average is under 70, display the message "FULL NAME, you are not passing the class".
