Question

Assuming that a user enters 64 as his marks obtained, what is the output of the following code snippet? int main() { int score = 0; cout << "Enter your score: "; cin >> score; if (score < 40) { cout << "F" << endl; } else if (score < 50) { cout << "D" << endl; } else if (score < 60) { cout << "C" << endl; } else if (score < 70) { cout << "B" << endl; } else if (score < 80) { cout << "B+" << endl; } else { cout << "A" << endl; } return 0; }

a) D b) C c) B d) A

Answer 1

Answer is option C) B

Here, this program is executing if else if statements for finding out the grade according to user input.

When a user enters 64,

1-> if(score < 40), then it will not be true, so next will be implemented.

2-> else if (score < 50), then it will not be true, so next will be implemented.

3-> else if (score < 60), then it will not be true, so next will be implemented.

4-> else if (score < 70), since, score is 64, so this statement will be true, and hence, cout << "B" will be implemented.

Which will give us output B.

So, answer is C) B
