It just comes back asking : "How should we call you?:"


I repeat my previos answer:

Probably because you have a loop or a recursive call to Quiz::Start(), however, I don't see any loops or recursive calls in the code in the last code you posted.


At line 19 in you full post, you've declared bScience as a member of your Quiz class, but line 1 of your last post shows bScience to be a global function, not a member of the Quiz class. However, this does not explain the problem you're seeing.

Since that message is not displayed by bScience(), your problem is elsewhere.

If you want futher help, you're going to need to post your current code in its entirety.

Line 71: You call q1.start().
Line 76: You call q1.start() again. When you return from the call at line71, you're going to fall through to the call at line 76. What do you think is going to happen the second time you call q1.start()?

You mean to say that when the second time I call q1.start() it's due to this that my program is going back asking userName?

1. When I remove line 76, after asking the subject it comes back to the code.

2. When I remove line 76 and add the following in the bScience() function:

it comes back to the code. Why it isn't executing?
AbstractionAnon (6954)
You mean to say that when the second time I call q1.start() it's due to this that my program is going back asking userName?

Yes. If you call q1.Start() twice, you're going to ask for user name twice, because that is what q1.Start() does.

Why it isn't executing?

Where do you call bScience()? You have to call a function for it to execute.

BTW: If you add a call to bScience() the way you have it, you're going to get linker errors. As I pointed out before, you have bScience() as a global function. Whereas your function declaration says it's a member of Quiz. For the second time, change line 214 to void Quiz::bScience().

It's doing the job perfectly. One thing is still not cleared, I've the following text in the .txt file:

What's your scientific name?

a> Homosoyans
b> Homosapiens
c> Humane
d> Sapiens

But when the file opens and shows the content, it's like this:

What's your scientific name?a> Homosoyans ...large gap... b>Homosapiensc>Humane
d> Sapiens

I want to look it as it's in the file...How?
What's your answer?:[/tt]

Thanks, it worked!

Now, I want to compare the actual answer to the userAns using Data File Handling.
For example, the answer to the first question is 'b', how can I compare it with the answer provided in the file 'bScAns.txt'? Or should I go to some other method?

Why aren't the lines 176, 177 and 178 compiling?
And, how to display one question at a time present in 'bScQues.txt' file if there are 10 in total. As I've said before, one question, then answer compare then again second question, then compare...Will a loop help?

What do you mean lines 176-178 are not compiling? I see nothing wrong with them. If you're getting compile errors on them, please post the exact errors messages from the compiler.

What I do see is that lines 176-178 are immediately followed by a call to clrscr().
What is happening is that the lines are displaying, but you immediately erase them so you never see them. I suggest you spend a few minutes actually reading your code.

As for reading from the file and comparing answers, you going to have to do that yourself. I'm not going to write the code for you. If you get stuck, post what you have.

Even when I remove clrscr() in line 174, I can't see the three line 176-178 before the file is opened.

And how to display one question at a time present in 'bScQues.txt' file if there are 10 in total? Should I use a for or while loop?

Removing the clrscr() at 174 is not the problem. The issue is the clrscr() at 179.
READ THE CODE. You display the three lines, then clear the screen.
How do you expect to see what you just displayed?

Should I use a for or while loop?

Either will work.

Removing the clrscr(); at 179 worked!

When I'll finish the question display code, I'll post it here.

Line 11: You're trying to read the question from cin (standard input), not the stream you opened on line 10.

Line 17: What is it you're trying to do here? ans is a simple char. It does not have a get method. Are you trying to get a char from your f2 stream?

Line 18: You're trying to compare an array (ch) to a simple char (c). That won't work. ch contains your question. Why are you comparing anything to your question? This is a good example you why you should use meaningful variable names. ch doesn't indicate anything meaningful. If you had used a variable name such as quest to hold your question, it would have been obvious that this line didn't make sense.

When I change cin to f1 it results the same error.

By what should I replace this to?

While executing, the question repeats 10 times mainly because of for( int i=0;i<10;i++). I included this because I want the 10 questions to be printed seperately. I know it's wrong, but I can't figure out the exact code for this. Could you please give me a hint?

You're currently opening each file 10 times. Each time you do so, you're positioned at the beginning of file.

Move lines 10-11 and 17-18 to in front of line 8.

What is line 22? That is a function declaration, not a function call.

Done. moved. But while I write the following lines I get an error- identifier bScience cannot have a type qualifier..in front of line 2 in above code. Why so? (After line 167 in KVaibhav01 (17))

while I write the following lines I get an error- identifier bScience cannot have a type qualifier..in front of line 2 in above code.

Don't have enough context to evaluate that statement.

Lines 30,48. If the user enters S, you will execute both iScience() and iSports(). I pointed this out to you once before.

Lines 62-80. Ditto.
