Question

Can you please write a C++ program in codeblocks for this problem? Thank you.

Practice) a. Using a do statement, write a program to accept a grade. The program, sh e continuously as long as an invalid grade is entered. An invalid grade is any grade less than 0 or greater than 100. After a valid grade has been entered, your program should display the value of the grade entered. b. Modify the program written for Exercise la so that the user is alerted when an invalid grade has been entered. c. Modify the program written for Exercise lb so that it allows the user to exit the program by entering the number 999. d. Modify the program written for Exercise lb so that it automatically terminates after five invalid grades are entered.
