Can someone explain to me how exactly this code works?

Question

This was in C# challenge, it returns 1500, and I don't know what is going on here :c

int a = 1500;
int b = 2000 % 1;
//int c = 1000;
{
if(b>a)//c+)
Console.Write("2000");
}
{
Console.Write("1500");
}
/*{
Console.Write("1000");
}*/

Answer 1

Let's remove the parts which have been commented out.

int a = 1500;
int b = 2000 % 1;

{
if(b>a)
Console.Write("2000");
}
{
Console.Write("1500");
}

This should now be clear why the output is 1500.

Answer 2

a=1500;
b=2000%1=0;

Since, 0 is not bigger than 1500,
thus only
Console.WriteLine("1500"); runs

Answer 3

If you are writing a songle line statement after if or else, then adding curly braces are optional else mandatory.
This program is doing useless things, so ignore as Hasty Rei said.

Answer 4

1) If you have no braces after if statement, only the first statement following the if statement will be executed if condition is fulfilled.

2) They do nothing. :D

Answer 5

Thanks, I'm learning C# from yesterday, you've helped a lot! ^^

Answer 6

This part I understand, but
1. why there are no parentheses after if statement?
2. why if statement and write 1500 func are in parentheses which seems to do nothing?
