I need some C# help

[mexxer-2]

Hi guys,

I started learning programming in school and I got some tasks for my homework.
I solved the easier tasks, but I can't solve "harder" ones.
I hope you will give me some instructions.

Thanks

1. task
Program which writes my name 10 times.

2. task
Program which writes numbers 1-10

3. task
Program which writes numbers 0-100 and only shows even or odd numbers.

You want us to do your homework?  Seriously? You made me laugh hard.

On a serious note look at your book, or online all of those are easily done.  You are starting off easy in C#.  If you don't understand the basics like this at end of semester you will be hurting very bad on keeping up.   Each lesson in programming builds on one before it.

you need help in c? are you serious ?

1. task
Program which writes my name 10 times.

use loop . while loop preferred . sorry i will tell you other ones later i m on mobile at the moment if you say i can write whole programs for all of them

I didn't ask you to do my homework. I don't want you to do it for me. I asked for instructions only

Each of these exercises requires you to understand looping constructs.  The first one asks you to repeat a task 10 times.  The second asks you to count to 10 and the third asks you to ... well, I think you wrote the third one down wrong because showing only even or odd numbers will show them all - unless you're supposed to prompt the user to enter whether or not he wishes to see evens or odds?  That seems a bit more complicated than the other two which are simply asking you to understand loops.

Loops in programming are very similar to how you'd think of repetitive tasks in your life.  For example, let's look at the first task.  How would you do it on paper (without using computer code)?

1) Look to see how many times your name has been written
2) If your name has been written fewer than 10 times, write your name
3) Repeat

You could also express this as a sentence:

I will repeatedly write my name until I have written it 10 times.

By doing this, you have given yourself a task that must be repeated until a condition is met.  Let's think of that sentence in another way:

While I have written my name fewer than 10 times, write my name.

So... you need a way to count how many times you've written your name, a way to write your name, a way to increment your counter, and a way to repeat those tasks.

We would start our counter at 0 because you haven't written your name yet.  Now, you start your repeating loop.  Is the counter less than 10?  If yes, write your name and increment the counter.  Do it again.  Now the counter is 1.  Is that less than 10?  Yup.  Write your name and increment the counter.

Now let's think of it in terms of code:

Initialize counter to 0.
While counter is less than 10:
 * Write my name
 * increment counter

I hope this helps, and allows you to follow along with your other 2 tasks.

@jonnybravo0311, you helped me a lot. Thanks

We have 2 hours of informatics weekly. Professor tells us to write some material from the books in our notebooks and when we are done, we are free.

I highly suggest buying a new book if that one is not good.  Not all books are equal on teaching programming. 

I suggest looking at Amazon.  There are some great books, that will make learning much easier if your book is crappy.

OK. I think I will do it, because I have done same thing with excel.
Thanks.

OK, I have done it with numbers.


Can you give me some hint how to do it with text?
 

Use a for loop instead of a do and while loop.:

for (; ; )
         {
            Console.WriteLine("Your name");
         }

{

  int n;
  n=10;
  While (n)

    {
     printf (Your Name);
     n = n-1;
    }

}

LOL! This is a C program and not C#.

I forgot to mention. We need to use do while loop.

Oh, I see, I didn't even knew this exists, it's the Microsoft spin-off of C...

Sorry for wasting my time.

The text one will be very similar.  Instead of printing out your counter variable, you just print the text over and over again.

Code:

int i = 0;
do {
  Console.WriteLine("jonnybravo0311");
  i++;
}
while (i < 10);

You'll have to explain the third task a bit more clearly.  Are you supposed to prompt the user to actually tell you whether to show odds or evens?  Or are you just supposed to count to 100 by odds first, and evens second?

Think about that third task and try to put it into terms like I did for your first task.  How do you count only the odds, or only the evens in your head?  How would you do it on paper?

One thing I might suggest is comparing code to what instructor used.   In programming there are ton's of ways to solve a solution.  But if everyone uses about the same code shown in class and you use different it will bring up questions.

Also are you allowed to use laptops during class?   If you are I suggest bringing one and trying to write the programs as instructor does.   That helped me alot then I had a version to compare to.

Be sure to get this book if you're serious about programming: http://www.amazon.com/Primer-5th-Edition-Stanley-Lippman/dp/0321714113

Even though it's C++ it's got tons of information and glossaries about all the programming vocubulary etc. you need and there are free .pdfs around on the internet if you really want it. I particularly recommend this one just because it explains all sorts of terms to you in actual English so you can have a conversation with other programmers and not feel completely lost.
