I don't quite get this, it means that if I have an array, say 3 elements, when I say foreach($elements as $element) every one of this three elements will go one by one to the variable $element?

? : are called Ternary Operators.
ex.
var = booleanExp ? ValueIfTrue : ValueIfFalse;
and that ? literally means "Asking a Question" Asking if the Boolean Expression is True.
If the Boolean Expression returned true, the Value for "True" will be assigned to the variable.
If the Boolean Expression returned false, the Value for "False" will be the one that'll be assigned to the variable instead.
I'm not asking a question, I just wanna share this to you guys 😁

public static void main (string[ ] args)
i have understood little bit that public means for whole method.
static?
void?
main is a method which creates a string array named args. why the name args?
please explain and correct if i am wrong?

x = 42;
int num = 0;
while (num <3)
Consele.writeline (x);
num++;
int x = 42; is just an int with an asigned value of 42
int num=0; is what initiate the count for the while loop
while (num < 3); means 0<3 true, 1< 3 true, 2<3 true, the loop end at 2 bc 3 <3 is false
consele.writeline (x) will display 42 while num < 3
num++ will execute and then add 1 to check if the while loop still true, but it stop at 2, bc 3 makes it false.
so the consele.write will write 42 three times. x=42, remember the (x)
