Compile but cant print out answers

I got it finally to work....If I enter a number other than 0-100 it gives an error and asks for a new number. I was looking in my book and ran across a statement, which is what I used, but is there a better way to make it say failing or passing vs just saying failing, no passing yes...ect?

Code:

	int index;
	int grade;
	int score [NUM_STUDS];

	cout << "Please enter 5 test scores on a grading scale of 0-100 points. "<< endl;
	cout << "I will tell you if the test scores are passing or failing." << endl  <<endl; 


	for (grade =0; grade <NUM_STUDS; grade++)

	cin >> score[grade];

{
	cout << "You entered " << score[grade] << endl;
	cout << "It must be between 0-100." << endl;
	grade--;
