Answer 1

An operator, in computer programing, is a symbol that usually represents an action or process. These symbols were adapted from mathematics and logic. An operator is capable of manipulating a certain value or operand.

There are several classifications of operators and each of them can have one or more operands, a specific data that is to be manipulated.

• Assignment Operator: This refers to the "=" (equals) sign and assigns a variable. A variable is the framework of the information.
• Arithmetic Operators: These include "+" (addition), "-" (subtraction), "*" (multiplication), "/" (division), "\" (integer division), "Mod" (Modulo) and "^" (exponentiation).
• Boolean Operators: These make use of "And" (logical conjunction), "AndAlso" (short circuit And), "OrElse" (short circuit Or), "Or" (logical inclusion), "Not" (negation) and "Xor" (logical inclusion). These symbols are also known as logical operators.
• Relational Operators: These include ">" (greater than), "<" (lesser than), ">=" (greater than or equal to), "<=" (lesser than or equal to), "==" (equal to), "<>" (not equal to), and "Is" (comparing references). These symbols are used to evaluate variables.
• Bitwise Operators: These are used in manipulating bits of a binary value and are not always used in programming. These include the symbols "Not" (bitwise negation), "Xor" (bitwise exclusive or), "And" (bitwise and), and "Or" (bitwise or).

computer programming, operators are constructs defined within programming languages which behave generally like functions, but which differ syntactically or semantically. Common simple examples include arithmetic, comparison, and logical operations.
