Am I reading this right?

in this code : for (int i =0; i < 5: i++) { Console.WriteLine(i); } So am i understanding this right?: First you have to declare statement 1 witch is int i = 0; once this is declared the complier execute the code block that contains Console.WriteLine(i); statement 2 defines the condition for executing the code block. statement 3 is executed everytime after the code block has been executed?

Am I understanding this right *

Angius•5mo ago

Basically, yeah

for (initial state; run condition; state change)
{
    // ...
}

for (initial state; run condition; state change)
{
    // ...
}

is how you could describe a for loop

Thanks for your reply I will now go over it ! But is this also true

Like is statement one ran and then the code block runs after that statement 2 and 3 are ran by the compiler ? @ZZZZZZZZZZZZZZZZZZZZZZZZZ Like statement 1 first ran and then the code block is ran behind the scene and then statement 2 and 3 ran? Can someone answer my question c: ?

See for yourself

Sorry buddy didn’t mean to offend you

Angius•5mo ago

You did not It's just a word of advice that if you expect people to always answer the minute you post a question, you're not always gonna get that

JexsOP•5mo ago

Okay 🙂 is a string literal , litteraly just something along the lines of "Console.WriteLine("Hello how are you today")

Angius•5mo ago

A string literal is literally just a string So "hello world"

JexsOP•5mo ago

okay ty 🙂 what does null mean? also are + ,- ,/ , * considered unicode characters

ty for the link can break be used to exit from a for loop, while loop, a do while loop, a for each loop ? like all of theses?

Angius•5mo ago

From any loop, yes Most characters fit the Unicode range

Angius•5mo ago

And when it comes to null...

JexsOP•5mo ago

thank you for your reply you've been really help ful! is there a website where you can paste your code and it lines up all the brackets for you automaticallyh i messed up my brackets and it feels like a pain trying to figure out where i should put oned one*

blueberriesiftheywerecats•5mo ago

Yes, imagine if int i = 10 and statement 2 is i < 5, why would it even run? So yes im sure Check format keybindings in your ide

JexsOP•5mo ago

@blueberriesiftheywerecats "For the loop, starting with int i equal to 0, while i is less than 10, increment i by 1 after each iteration. Inside the loop, print the value of i to the console." @blueberriesiftheywerecats "For the loop, starting with int i equal to 0, while i is less than 10, increment i by 1 after each iteration. Inside the loop, print the value of i to the console." is this the correct way to read this for (int i = 0; i < 10; i++) { Console.WriteLine(i); }

blueberriesiftheywerecats•5mo ago

Yes

ty mate 🙂

To format your code in Visual Studio, Visual Studio Code, Rider, use the following shortcut:

Visual Studio        CTRL  + K     + D
Rider / Resharper    CTRL  + ALT   + L
Visual Studio Code   SHIFT + ALT   + F

Visual Studio        CTRL  + K     + D

for (a; b; c){d}

for (a; b; c){d}

a;
while (b)
{
    d;
    c;
}

a;
while (b)
{
    d;
    c;
}

Gokul•4mo ago

so the order is statement1(int i=0) , then statement2( i<5), if statement 2 satisfies code block is executed and then statement 3, if statement 2 result in false , it will directly skip the code block and statement 3.
