C# Counter

[joshuawi99]

Hey i have to write a little console Porgramm in C# for school that count up to your input.

 

So when the input is 5 for example the result should be like this:

0 1 2 3 4 5

 

and so on...

 

can somebody help me how i get this?

 

Thanks!

This sounds like homework or an assignment, so I'm not going to answer it directly. Read up on loops and you should be able to figure this out.

Well, I'm sure your teacher went over loops before handing you this assignment. So I don't feel too bad repeating @tikkers statement that you should look into loops.

However, I will go to the length of teaching some things about the different types of loops available in C#:

• Foreach loops
• While loops
• For loops
• Do while loops

Foreach Loops:

Spoiler

A "foreach" loop iterates over some items in a collection, doing some action on each of those items. You cannot assign anything to the elements of the collection inside a foreach loop.

Here's a simple example:

SomeCollection myCollection = new SomeCollection();
// add things to myCollection

foreach (type t in myCollection)
{
  // do some action. Action cannot assign to variable t
}

 

 

While loops:

Spoiler

A while loop iterates over some block of code as long as some condition is true. You can assign to any variables that are in scope inside a while loop.

 

Here's a simple example:

// this is a fizzbuzz program

int myInt = 0;

while (myInt < 101)
{
  if ((myInt % 3 == 0) && (myInt % 5 == 0))
    Console.WriteLine("FizzBuzz");
  
  else if (myInt % 3 == 0)
    Console.WriteLine("Fizz");
  
  else if (myInt % 5 == 0)
    Console.WriteLine("Buzz");
  
  else
    Console.WriteLine(myInt);
  
  myInt++;
}

 

 

For loops:

Spoiler

A for loop is the same thing as a while loop. Infact, the compiler output for the while loop example above is exactly identical to the compiler output for the for loop example below. The difference is that a for loop lets you describe all of the conditions that affect the iteration (the variable, the condition, and the action on the variable) in the loop declaration. 

Here is the while loop example, modified to use a for loop:

for (int myInt = 0; myInt < 101; myInt++)
{
  if ((myInt % 3 == 0) && (myInt % 5 == 0))
    Console.WriteLine("FizzBuzz");
  
  else if (myInt % 3 == 0)
    Console.WriteLine("Fizz");
  
  else if (myInt % 5 == 0)
    Console.WriteLine("Buzz");
  
  else
    Console.WriteLine(myInt);
}

 

Do While loop:

Spoiler

A "do while" loop is the same as a while loop, except, the do while loop is guaranteed to execute atleast one time. To see why this is different than a while loop, we need to examine a simple while loop. Take this one for example:

while (myBool)
{
	// Do stuff
}

 

In the above example, if myBool is false before the first iteration, this loop will never execute. If we need the loop to execute atleast once regardless of the value of myBool, then we would use a do while loop:

do
{
	// Do something
} while (myBool);

In this example, the loop will execute atleast once, regardless of the value of myBool before the first iteration.

Given these examples, which loop, or loops, do you think are applicable to your problem?

Thank you very much I got it !
