Ok, infinity, following are some of my answers that i think are correct.
1. A, 2. A, 3. i do not know, 4. F, 5. C, 6. do not know, 7. C, 8. I do not know, 9. I do not know, 10: D, 11. C, 12. I do not know, 13. B, 14. F, 15. C, 16. A, 17. A, 18. F, 19. D, 20. A
These are the answers i think are correct. Please help me out in this quiz. Thanks
>> 1. A,
Correct.
>> 2. A,
Correct.
>> 3. i do not know,
The question is about which of the operators are used to compare two values (equality, inequality, smaller than, etc.). Which of the ones listed is not such an operator ?
>> 4. F,
Correct. (it's still recommended though)
>> 5. C,
I assume this is correct, although the question is a bit weird. It's obviously a simple conditional statement (A). And in some ways you could see it as an "error in logic", since both cases have the same action.
>> 6. do not know,
What's the opposite of (a < b) ? In other words, if a is not smaller than b, then what can you say about a and b ?
>> 7. C,
No. If x is not larger than 3, is it possible that x is equal to 3 ?
>> 8. I do not know,
Start with the if statement. Is the condition true or false ? ie. wil the if block or the else block be executed ?
>> 9. I do not know,
You know that P is true, Q is false and R is true. What's the result of all listed statements ?
>> 10: D,
Is it possible to get into the if block ? For which value of 'age' ?
>> 11. C,
How would you replace a nested conditional structure with a switch statement ? What exactly does a switch statement do ? What would be the equivalent normal if statement ?
>> 12. I do not know,
Start with figuring out whether the if condition is true.
>> 13. B,
This question is confusing. I know which answer they are aiming for, but it's not as simple as that. Still, let's go for the answer they want ... Does the phrase make sense if you take your choice B ?
>> 14. F,
Correct. They are part of the standard I/O library.
>> 15. C,
Correct.
>> 16. A,
Another question that isn't really accurate. But again, I don't think A was the answer they intended ... Why would you hide a function ?
>> 17. A,
No. You can create a function without parameters :
void fun() { /* ... */ }
This function takes no parameters, and returns nothing.
There's only one of the 4 statements that makes somewhat sense.
>> 18. F,
Correct.
>> 19. D,
That's really a matter of taste and coding guidelines. But answer D makes the most sense indeed.
>> 20. A
Sounds good.
>> 3: A
!= is the "not equal to" operator - it tests for inequality ... so it is a comparison operator.
Think about the difference between the = and == operators.
>> 6: C
if a is not smaller than b, can a be equal to be ?
>> 7: A
Indeed. Use the same reasoning for question 6.
>> 8: This one i realy do not know.
Just take it line by line. The first line asks an input from the user, and stores it in the myNumber variable. The question mentions which value the user gives. Knowing that, what would happen with the if statement ?
>> 9: E
Indeed. All 4 of the statements are true.
>> 10: C
Yep. The if statement might as well not have been there, since it can never be true.
>> 11: B
Right.
>> 12: B
Good. You weren't tricked by the indentation of the 4th line :)
>> 13: I do not know the answer for this question and i thought B would be the best choice. It looks like C is also a candidate for right answer. Please let me know
Technically you're right that B and C are possible as answer, since it's indeed not possible for a function declaration or function definition to contain a main function (simply because those statements don't make sense at all). This is why I said the question is confusing.
But given that questions like these are looking for one specific answer ... which would you choose ? What is a main function used for, and when do you need it ?
>> 17: B
That's the one that makes somewhat sense indeed. With parallel implementation, they mean that multiple people/teams can work on different parts of the code at the same times.
Sorry for the delay - I've been on holiday for the whole weekend :)
>> 3:B
That's right. = is the assignment operator, while == is the equality comparison operator.
>> 5:A
As said earlier, I think the answer they were after was C (which you had originally). See http:#25253128
>> 6:B
If a is not smaller than b, does that mean that a is equal to b ?
I've got the impression that you're just guessing ... Don't guess - reason about it instead, and figure out the answer by logical deduction.
>> 8:B
Correct. Since 21 is larger than 4, the if block is executed, and the number 21 is displayed. After the if statement, the number is displayed once more.
>> 13:C
Try to answer the question I asked in http:#25254088 :
"What is a main function used for, and when do you need it ?"
The answer to that question will help you figure out the answer to question 13.
>> 16:D
D makes sense. So, let's go with that :)
Thank you Infinity. I also need help in writing the program for currency conversion with the following requirement. If you can help me out.
Write a currency Conversion Program that allows user to enter an amount of money (for a foreign currency of your choice), which is error checked as a valid entry, and then display its equivalency in U.S. Dollars. If on the other hand users input is invalid, the program should allow the user to reenter a new amount.
