C# basic concept problem

Question

int a=4;
int b =6;
b = a++
console.write(++b)

what will be the output???
and why??

Answer 1

It will be 5.
It is the position of the ++ that makes thr difference.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace SoloLearn
{
class Program
{
static void Main(string[] args)
{

int a = 4;
// a is now 4
int b = 6;
// b is now 6
b = a++;
// b first gets the value of a, and will be 4, and after that, a increases to 5
Console.Write(++b);
// b increases by 1 before it is printed, so it will be 5

}
}
}

Answer 2

`b=a++;`
is equivalent to
`b=a; a++;`

Answer 3

I found some detail information here:

> The result of the operation is a value of the same type as the operand.
