counters

Hey, guys. I have to follow a pseudocode tha includes loops etc. I got the loops so far, but I am having troubles with the counters.


counter is assigned 0
while counter is less than 5
display "\nI love computers!"
increment counter
endwhile

Code:

---

counter = 0
{
while
(counter < 5)
}
cout << "\nI love computers!";
{
increment counter
endwhile
}

---

I read up on it. But I don't really see how it works here.

The word "increment" means "add one to".

Yes, I know, but it's a variable. Like int counter 0 to initialize it?

So add one to it. Generally speaking, we use "+" to add things together, and "=" as you've seen assigns a value to a variable.

counter+; would come to my mind now. This stupid book dosen't tell me how to initialize the counter. Since it's a variable , I thought int counter = 0.

That's the initialization, int counter = 0. That's not going to help with the increment. counter is fine, + is fine -- so, what do you want to add to counter?

It's asking the user for his age. Then it decides if he/she can or can't vote.

Like.....

if age greater than 17
display "You can vote."
else
display "You can't vote."
endif

That's the first part, which i already have. So I think its counter+; I saw it also might be ++ ..depending on how you need to do it.

Right. So counter adding one is counter + 1; since you want to assign that back to counter, you get counter = counter + 1.

Now that we've done that, there is an operator "++" that adds one to a variable all in one shot.

Ok , so that's basically ok? For that particular part here...

Code:

---


counter = 0
{
while
(counter < 5)
}
cout << "\nI love computers!";
{
counter +;
endwhile
}

Your braces have gone awry. You managed to completely ignore my last post, so you should maybe read it this time. The only line you had correct (int counter = 0;) you managed to destroy.

That should be it.

Code:

---


counter = 0;
        while (counter < 5)
        {
        cout << " I love computers ! \n" ;
        count + 1;
        }

Green = good; Red = bad. You need to assign a new value to counter as you go through the loop.

ops sorry, I got counter. Don't know why I copied it. But no matter what I type in it always says I love computers.

Did you expect it to do something else?

And did you assign a new value to counter -- adding one is not enough, you have to put the answer somewhere.

Well, it's only supposed to say this if it's less than 5.

And no, I probably didn't. This is so confusing. I didn't think I have to do it since it's just supposed to say yes you can vote or no you can't, and if it's less than 5 just I love computers.
