Thread: prompt user for number of loops

Don't argue with Quzah. Really. He's got this annoying habit of making certain he's really right before posting, and even more so before getting into a discussion. I've never been able to prove him wrong on anything but minor details.

Yeah, he's one of the forum gods.

I most definately did read the problem. The sample code provides exactly this:

Yes, yes it was. Oh, by the way, that sample code we were talking about... yeah, that's exactly what it does.

Well at least we can agree on something.

What? What are you talking about? No one wanted to define a number in advanced and then have them pick a different one. That wasn't anywhere in the problem description. You're just making stuff up in an effort not to be wrong. That's just silly. No one wanted that but you.

You just keep telling yourself that.

To further the point, I'll provide a full explanation of the origional post, since you've decided to start quoting fragments of text to support your fiction:

for example, I know that if I set #define MAXCOUNT 100, it will loop 100 times. What would i put for the user to select the number of times they want it to loop?

This means:

"I don't know how to prompt the user for a number, which will be used to control the number of loop executions. For example, I know if I use a #define, I can then insert that into a loop, like so:

Code:

#define MAXCOUNT 100
int x;
for( x = 0; x < MAXCOUNT; x++ )

However, I am not sure how to replace the MAXCOUNT portion with a number that the user chooses instead."

Reading comprehension for the win! I mean, come on! That was easy to understand. They .... ah, that's it, isn't it? They used complete sentences, punctuation, and while they did slip in a lower case i, they didn't use enough "u", "omg", "plz", "k", "thx" and the like. Typical.

See, CornedBee can comprehend the OP's post. What's your problem? Oh, right, he's not trying to prove he's right, like you are. Even though you say you're really not. *snicker*

As I like to put it, "Never argue with a pedant."

That being said, I am occasionally wrong. Just not now.

What i need to do is lets say you are a teacher, and you have a X number of students, you want a program that calculates the class average, so how do i prompt the user to say ok, i have 25 students, and then enter your 25 grades as prompted, then it will print out the average. The only part is how do i get to the prompt part first.

So take a moment to think about how you'd get it to use that number. It's really quite simple:

Code:

ask for number
store number in variable

loop using that number as shown
    do stuff

Just don't change the value of the variable after you've read it in. Then use that variable, as illustrated in the first example, and many times afterwards, to control loops as you please.

Post some code if you still can't figure out. Be sure to explain what it is you want. Be sure to use tiny words, so that maybe this time Adak will be able to follow along. (Just between you and I, he seems to be a little slow in the head. If you know what I mean. )

From the thread's originator:

Nice try, but you fail. Read the first post. I can selectively quote pieces I need to make my argument, but I don't have to. My point has already been made. It was made in the first post, with the first reply being the correct answer.

See that? First post, first line. "How do I prompt a user to choose the number of loops they want. Bam! Reading comprehension for the win! First post second line, "I know that if I set #define MAXCOUNT 100 it will loop 100 times. What would I put for the user to select the number of times they want it to loop?

You fail, moron. It was asked and answered in the first post.

Next, you say:

100% false! ........ing copy-paste, compile. It works. You're wrong.

The only way you are even remotely correct here is if you're trying to say your understanding of what the origional poster really wanted is:

"I want the user to be able to edit the line "#define MAXCOUNT x" so that they can compile the program with their own hard coded value."


Quzah.

If you want to argue with the most venerable, perfect, correct, distinguished member on this board, at least do it without the big red slushy font.

To wonderpoop, one more time,

Code:

assume you have a number X
scanf("%d", &X);

for(i = 0; i < X; ++i)
{
    /* instead of looping MAXCOUNT times, this will now loop X times, */
    /* simply because you replaced MAXCOUNT with X. Got it? */
}

Adak, what are you thinking? Quzah is right, he takes the time to formulate his answers, and he doesn't use size 100 red font.
