C++ PROGRAM/ MY QUESTION IS 6.57

6.56 (Computer-Assisted Instruction) The use of computers in education is referred to as com- puter-assisted instruction (CAI). Write a program that will help an elementary school student learn multiplication. Use the rand function to produce two positive one-digit integers. The program should then prompt the user with a question, such as How much is 6 times7 The student then inputs the answer. Next, the program checks the student's answer. If it's correct, display the message "Very good!" and ask another multiplication question. If the answer is wrong, display the message "No. Please try again." and let the student try the same question repeatedly until the student finally gets it right. A separate function should be used to generate each new ques- tion. This function should be called once when the application begins execution and each time the user answers the question correctl 266 Chapter 6 Functions and an Introduction to Recursion 6.57 (Computer-Assisted Instruction: Reducing Student Fatigue) One problem in CAI environ- ments is student fatigue. This can be reduced by varying the computer's responses to hold the stu dent's attention. Modify the program of Exercise 6.56 so that various comments are displayed for each answer as follows: Possible responses to a correct answer: Very good! Excellent! Nice work! Keep up the good work! Possible responses to an incorrect answer: No. Please try again Wrong. Try once more. Don' t give up! No. Keep trying Use random-number generation to choose a number from 1 to 4 that will be used to select one of the four appropriate responses to each correct or incorrect answer. Use a switch statement to issue the responses
