Question
(Write a program, and show the output too) C programming
You will be writing a simple Bee application. The application will display question 1, wait for the user to type a response, it checks if it is correct or not. if correct, it will increment the score by one. otherwise, it will go ahead with the next question. You would read any 10 questions from below. Then, store them in an array of structures: store one question in each cell . Then, store them in an array of structures: store one question in each cell
You have both Training Mode and Quiz mode.
//You would overhaul the version 2 to read 10 questions from the file.
//
In above there are 50 questions.
But you would select only 10 random questions
There are two modes: Training and Quiz mode
The requirements are same as in version 2 for these modes

1. Extend the code
2. Ask the user, if he wants to practice or Take the real quiz. There are two modes of operation: Practice mode and QUIZ MODE.
3A. In the practice mode, the user is given three chances to provide the correct answer. Score is incremented only he answers correctly in those three chances. Otherwise, show him the correct answer and proceed.
3B. In the Quiz mode, there is no additional chances given. Score is incremented only if he answers correctly the first time.
4. The order of questions is random. use any method. The order of questions should be different each time you run.
