Question

PLEASE, CLEARLY EXPLAIN THE ANSWER OF THE FOLLOWING QUESTION: -

What is wrong with the following code snippet?

cout << "Please enter a number: ";

cin >> b;

if (b > 100)

   cout << "Your number " << b << endl;

   cout << " was greater than 100" << endl;

1. It has a syntax error.
2. Nothing is wrong.
3. Braces should have been included after the if() statement to clarify which statements are conditional.
4. The comparison should be (b < 100).

Answer 1

If there is no {} after if statement then only the first statement after it consider to be in the if block.

So, we have to use {} and keep two statements inside it.

FIX:
-------
cout << "Please enter a number: ";
cin >> b;
if (b > 100){
   cout << "Your number " << b << endl;
   cout << " was greater than 100" << endl;
}

Answer:

Braces should have been included after the if() statement to clarify which statements are conditional.
