>> (BitWise Shift Shift): Đây cũng là toán tử nhị phân, tức là hoạt động trên hai toán hạng. Toán tử BitWise Shift có hai số, phải thay đổi các bit của toán hạng đầu tiên, toán hạng thứ hai quyết định số lượng địa điểm thay đổi.

The operators are first converted to bit-level and then calculation is performed on the operands. The mathematical operations such as addition , subtraction , multiplication etc.
Các toán tử bitwise khác nhau là gì?Và, hoặc, xor, không, dịch chuyển và mặt nạ là 6 toán tử bitwise.Mỗi bit trong số được coi là 0 hoặc 1 bởi các toán tử, hoạt động với biểu diễn nhị phân của các số. are the 6 bitwise operators. Each bit in the number is regarded as a 0 or 1 by the operators, which work with the binary representation of numbers.
