Variables | Tutorial This section describes the expressions, types, and variables of the C # language. This lesson aims to achieve the following objectives:
1. Know what a "variable" is
2. Learn simple types of C #
3. Have a preliminary
All integer variables default to signed integers, JavaScript bitwise operation, is the use of 32-bit signed integer, which means that the result of its conversion is also a 32-bit signed integral typeIn JavaScript, all integer numeric variables are
Operation

result ^= expression
Parameters
Result
Any variable .
Expression
an arbitrary expression .
Description
Using the ^= operator is

Two types of annotation characters can be used in Transact-SQL.
The ANSI standard annotation character "--" is used for single-line annotations;
