Topic: Operators in C and C Plus Plus


In the News (Tue 21 May 13)

  
  Operators in C and C++ - Wikipedia, the free encyclopedia
Those operators that are in C, with the exception of the comma operator, are also in Java, Perl, C#, and PHP with the same precedence, associativity, and semantics.
Operators on the same row are evaluated with the same precedence, in the given direction.
The binding of operators in C and C++ is specified (in the corresponding Standards) by a factored language grammar, rather than a precedence table.

 C plus plus operators - DmWiki
An operator is a symbol or a set of symbols that define how to treat data in relation to other data stored in the program.
Operators in C++ are mostly made of characters that are not part of the alphabet, but are part of the standard ASCII set and available on all keyboards.
In the early C compilers, the three previous expressions probably produced different executable code depending on which one was used.

 Operators in Java by Richard G Baldwin
An operator that operates on one operand is called a unary operator, and an operator that operates on two operands is called a binary operator.
A - False: The increment operator is a unary operator.
A - The assignment operator is a binary operator.

The and operator is known as the Bitwise AND operator.
The ^ operator is known as the Bitwise XOR operator.
This is because you are operating on 2 integers.

 overloading
Although the prototype of a function operator+ can seem obvious since it takes what is at the right side of the operator as the parameter for the operator member function of the object at its left side, other operators may not be so obvious.
Operators obey the precedence, grouping, and number of operands dictated by their typical use with built-in types.
The first argument for member-function overloaded operators is always of the class type of the object for which the operator is invoked (the class in which the operator is declared, or a class derived from that class).

 Linguistics 482 - Prolog Operators   (Site not responding. Last check: 2007-11-02)
Operators are special Prolog structures that have operator signs as their names.
Operators can be represented according to the customary format for structures, that is, by writing the structure name followed by its arguments, with these being enclosed in parentheses and separated by commas.
The operands of the addition operator, that is, the numbers that are to be added together, are the arguments of the structure named by the plus sign.

 C - LQWiki
C was designed by Dennis Ritchie during the early 1970s and immediately used to reimplement Unix.
C is often described, with a mixture of fondness and disdain varying according to the speaker, as “a language that combines all the elegance and power of assembly language with all the readability and maintainability of assembly language”.
C has for a long time been one of the languages of choice.

 Operators
A table of operator associativity and precedence appears in the next section.
The relational operators < (less than) > (greater than) <= (less than or equal to) >= (greater than or equal to) yield ``1'' if the specified relation is true and ``0'' if it is false.
The == (equal to) and != (not equal to) operators are analogous to the relational operators; however, they have lower precedence.

 Operators and Assignments
the modulo operator gives a value which is related to the remainder of a division.
For AND(&&) operation, if the left operand is false, the result is definitely false, it is not necessary to evaluate the right operand.
For OR() operation, if the left operand is true, the result is definitely true, it is not necessary to evaluate the right operand.

 C++ - Wikipedia, the free encyclopedia
C++ supports this (via member functions and friend functions), but does not enforce it: the programmer can declare parts or all of the representation of a type to be public, and is also allowed to make public entities that are not part of the representation of the type.
This is partly because the C++ grammar is not LALR.
C++ is also sometimes compared unfavorably with single-paradigm object-oriented languages such as Java, on the basis that it allows programmers to "mix and match" object-oriented and procedural programming, rather than strictly enforcing a single paradigm.

 SMM: Reference Operators; spreadsheet models
The three reference operators are the range operator, the union operator and the intersection operator.
The range operator (colon), which is an infix operator, is used to join two cell references to make a range reference.
Because the union operator is represented by a comma, which is also used to separate arguments of functions, you usually have to surround the expression with parentheses to prevent ambiguous interpretation of the expression by Excel.

C# is a lot like Java and a Java developer will find the transition between the two languages to be very simple.
C# allows you to create explicit or implicit casts between classes that would not normally be permitted.
C# uses the C++ model for polymorphism which means you must take positive action to make a method eligible to take part in polymorphism.

 Operators
The arithmetic operators are the most basic mathematical operators.
Bitwise operators takes two bit patterns of equal length, and produces another one of the same length by matching up corresponding bits (the first of each; the second of each; and so on) and performing the logical operation And, Or or Xor on each pair of corresponding bits.
The operations bitshift left (a << b) and bitshift right (a >> b) do shift the (binary) bits of the number a over a number of positions given by b.

 Operators
All-purpose assignment operator, which works for both arithmetic and string assignments.
# = as a test operator if [ "$string1" = "$string2" ] then command fi # if [ "X$string1" = "X$string2" ] is safer, #+ to prevent an error message should one of the variables be empty.
An operation that takes a variable outside these limits will give an erroneous result.

 perlop - perldoc.perl.org
Operator associativity defines what happens if a sequence of the same operators is used one after another: whether the evaluator will evaluate the left operations first or the right.
Operators borrowed from C keep the same precedence relationship with each other, even where C's precedence is slightly screwy.
The right operand is not evaluated while the operator is in the "false" state, and the left operand is not evaluated while the operator is in the "true" state.

 C++ Operator Precedence
The operators at the top of this list are evaluated first.
It is important to note that there is no specified precedence for the operation of changing a variable into a value.
The bottom line is that you should not use the same variable multiple times in a single expression when using operators with side effects.

Now that this well-kept "Better C" secret is in the public, I suspect there will be nothing short of a complete revolution in the world of C programming.
He was obviously trying to make C more self-documenting, which we all know is just an excuse for longer keywords that makes the language slower to code.
And attempts to use the preprocessor to rape C are not new.

 Practically Groovy: Smooth operators
As any C++ developer will tell you, this stuff is both handy and fun, although it should be approached with a healthy dose of caution.
operator in Groovy is already overloaded in a few different areas, especially when it comes to collections.
As you've seen, operator ad hoc polymorphism, or operator overloading to the rest of us, can be quite powerful if carefully employed and documented.

 Synopsis 3: Summary of Perl 6 Operators - perl6:
Parentheses (with or without a dot) turn the list operator into a function call instead, and all the function's arguments must be passed inside the parentheses (with the sole exception of an adverbial block, which may follow the parentheses).
Regardless of the precedence of the base operator, the precedence of any assignment operators is forced to be the same as that of ordinary assignment.
A unary hyper operator (either prefix or postfix) has only one hyper marker, located on its argument side, while an infix operator always has one on each side to indicate there are two arguments.

 The Power of JavaScript: Operators
An operator is a symbol with an associated known operation to the language.
The + is a symbol, and the associated operation is adding two numerical values like 3 + 9; the numerical values are what we call the operator's operands.
The addition operator is called a binary operator because it works on two operands.

 Operator Precedence and Associativity
The associativity of operators refers to order in which repeated use of the same operator will be evaluated.
For example, the expression 1+2+3 will be evaluated as (1+2)+3 since the [quot ] + [quot ] operator associates the leftmost operator instances first.
In contrast, the statement A = B = C will first perform the B = C assignment, and then the result is assigned to A. Associativity should not be confused with precedence, which determines which one of different operators will be evaluated first.
