C ++到VB.NET的转换，剩余的<<和>>保留在数学语句中

Question

I converted some C++ code to VB.NET but there is residual use of ">>" and "<<" being used during the workflow which is throwing me off. How can I get rid of the << and >> in the example loops below and rewrite them in VB.NET without << and >>:

  For i As UInteger = q + 1 To L
     X(i) = X(i - q) Xor (X(i - q) >> CInt(q))
     For j As UInteger = 1 To q - 1
       X(i) = X(i) Xor (((b >> (q - 1 - j)) And 1) * X(i - j))
     Next j
  Next i

And other uses of << such as:

  For i As UInteger = 1 To L 
    X(i) = 1 << (32 - i)
  Next i

Mathematically, I don't what C++ is doing with the << and >>.

Answer 1

They are bit shift operations, and you can leave them. They are the same in VB .NET.
