A logical operator is a symbol or word used to connect two or more expressions such that the value of the compound expression produced depends only on that of the original expressions and on the meaning of the operator. Common logical operators include AND, OR, and NOT.
What is an operator function?
An operator function is a user-defined function, such as plus() or equal(), that has a corresponding operator symbol. For an operator function to operate on the opaque data type, you must overload the routine for the opaque data type.

Why do we use + and & in a string?
Although the + operator can be used to concatenate two character strings, the & operator should be used for concatenation to eliminate ambiguity and provide self-documenting code. If + operator is used, there may be no way to determine whether addition or string concatenation will occur. The underlying subtype of the expressions determines the behavior of the + operator in the following way:
What order are operators shown in?
Arithmetic operators are shown in descending order of precedence. Parentheses can be used to control the order in which operators are evaluated. The default order, however, frequently achieves the correct result.
Why do we use parentheses?
Parentheses can be used to override the order of precedence and evaluate some parts of an expression before others. Operations within parentheses are always performed before those outside. Within parentheses, however, normal Operator Precedence is maintained.
What is operator precedence?
Operator precedence determines the grouping of terms in an expression. This affects how an expression is evaluated. Certain operators have higher precedence than others; for example, the multiplication operator has higher precedence than the addition operator:

Which operator follows a single operand?
Postfix operators, which follow a single operand.
Is x an L value?
So x is an L-value because it can appear on the left as we've just seen, or on the right like this: y = x; However, constants like 1 are R-values because 1 could appear on the right, but 1 = x; is invalid.

What is bitwise operator?
The Bitwise operators are used to perform bit-level operations on the operands. The operators are first converted to bit-level and then the calculation is performed on the operands. The mathematical operations such as addition, subtraction, multiplication, etc. can be performed at bit-level for faster processing. For example, the bitwise AND represented as & operator in C or C++ takes two numbers as operands and does AND on every bit of two numbers. The result of AND is 1 only if both bits are 1. (See this article for more reference).

Assignment operators are used to assigning value to a variable. The left side operand of the assignment operator is a variable and the right side operand of the assignment operator is a value. The value on the right side must be of the same data type as the variable on the left side otherwise the compiler will raise an error.

How does a compiler use Lex?
Be a Compiler: Compiler in our systems uses lex tool to match the greatest match when generating tokens. This creates a bit of a problem if overlooked. For example, consider the statement a=b+++c;, to many of the readers this might seem to create compiler error. But this statement is absolutely correct as the token created by lex are a, =, b, ++, +, c. Therefore this statement has a similar effect of first assigning b+c to a and then incrementing b. Similarly, a=b+++++c; would generate error as tokens generated are a, =, b, ++, ++, +, c. which is actually an error as there is no operand after second unary operand.
What is the rule for associativity and precedence?
There is a golden rule to follow in these situations. If the operators have different precedence, solve the higher precedence first. If they have same precedence, solve according to associativity, that is either from right to left or from left to right. Explanation of below program is well written in comments withing the program itself.
What is the meaning of :Unary minus?
They are used to increment, decrement or negate a value. – :Unary minus, used for negat ing the values. + :Unary plus, indicates positive value (numbers are positive without this, however). It performs an automatic conversion to int when the type of its operand is byte, char, or short.

Decrement and Increment Operators
- These operators are useful in minimizing calculation. n=n+1 can be truncated to n++. The operators are: 1. Increment (++) 2. Decrement (–) There is a significant difference in usage of the operators depending on the place of application. 1. Pre-increment operators: if we write the ++ operator before the variable name, one is added to the operand, and after that, the result is assig…
