Question
//ASSIGNMENT: overhaul the skeleton code below to read 10 questions from the file given using C.
//The file name: questionbank.txt //THIS IS THE FILE THAT HAS 50 QUESTINS. 10 SHOULD BE CHOSEN AT RANDOM. IT IS POSTED BELOW THE SKELETON.
//WHAT THE PROGRAM SHOULD DO:
1. THE PROGRAM SHOULD ASK THE USER IF HE WANTS TO BE IN TRAINING MODE OR QUIZ MODE
2. In the Quiz mode, there is no additional chances given. Score is incremented only if he answers correctly the first time.
3. 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.
4. The order of questions is random. use any method. The order of questions should be different each time you run.
HINT:
The function question_1 would be redefined as
int Question_1 ( int mode )
{
printf ( "What is the capital of USA ? 1. Atlanta 2. Washington DC 3. New York 4. Chicago " ) ;
int correctAnswer = 2 ;
int userResponse ;
if ( mode == TRAINING )
{
give him three chances.
}
else {
give him one chance
}
rewrite the rest of the functions
}
