The answers are stored in an int array and read from a file. In answers file 1 represent true and 0 false. Both array have same length. Student responses are recorded in another (third) int array. The answer and student response arrays are compared. Student score is computed. If student scores 60% or more the message is given that student passed. Otherwise message is given that student failed. */ const int MAX = 20; void openFile(ifstream & input, const string & message); int fillQuestionsArray(string questions[], ifstream & inq); int fillAnswersArray(char answers[], ifstream & inq); void fillResponseArray(const string questions[], int response[], int lenQ); int GradeResponses(const char answers[], const int response[], int len); void printAnswersAndResponses(const string questions[], const char answers[], const int response[], int len); int main(){ cout << "Welcome to the quiz." << endl; ifstream in; openFile(in, "TestBank.txt"); string questions[MAX] = {}; int lenQ = fillQuestionsArray(questions, in); { for (int i = 0; i < MAX; i++); } in.close(); openFile(in, "Answers.txt"); char answers[MAX]; int lenA = fillAnswersArray(answers, in); if (lenQ != lenA){ cout << "Number of questions and answers are different.
