An operand is the value that is being operated upon by an operator. For instance, the C++ increment operator (++) is a unary operator, which means it has only one operand, the variable that we wish to increment. This in the expression x++, x is the operand. The addition operator (+) is a binary operator and therefore has two operands. Thus in the expression x + y, x and y are the operands.

What is plus operator is it unary or binary?
There is no unary plus in C, but if there were, it would have only one operand, unlike the binary plus which has two: x = a + b; /* binary plus */ x = + b; /* unary plus -- not in C*/ x = a - b; /* unary plus */ x = - b; /* unary minus */
What is the difference between prefix and postfix increment operator in c plus plus?
Both the prefix and the postfix increment operators increment the operand. The difference is what is the value of the expression during the evaluation of the expression. In the prefix form, the value is already incremented. In the postfix form, it is not. int a = 1; int b = ++a; // both a and b are now equal to 2 int a = 1; int b = a++; // a is equal to 2 and b is equal to 1
Why there is only 2 plus in c plus plus languagewhy not 3 or 4 plus?
I assume by 2 plus you really mean ++. This is the increment operator which is used to increment the operand. If placed before the operand, the operator evaluates the incremented operand (prefix increment). If placed after the operand, the operator evaluates the non-incremented operand (postfix increment). +++ and ++++ are meaningless but are assumed to mean incrementing an increment. If you wish to increment an increment, you must use the compound expression ++(++) or (++)++. Thus for the variable x, prefix incrementing twice would be achieved with ++(++x), while postfix incrementing twice would be achieved with (x++)++. You can also mix the two, such as ++(x++) or (++x)++, both of which would increment x twice but would evaluate the increment of x. If postfix increment is not a requirement, it would be much easier to use the compound expression x+=n, where n is the amount you wish to increment. This is the same as saying x=x+n.
What represents the left hand side of a binary operator in c plus plus?
The left hand operand of a binary operator must represent a modifiable lvalue: void f (const int x, int y) { x = y; // error -- x is constant lvalue y = x; // ok }
What is the meaning for you plus plus plus in c?
C++ was originally called "C with Classes". In the C language, '++' is an operator that increments the operand, thus C++ is a shorthand way of saying C=C+1. In this case the operand is the language name itself, C, thus C++ literally means the "the successor to C". The ++ operator comes in two varieties: prefix and postfix increment. C++ is the postfix increment version, while ++C would be the prefix increment version. Both will increment the operand, C, however ++C evaluates to the original value of C while C++ evaluates to the incremented value of C. Which you use depends on whether you want the original value or the new value. Either way, C is incremented. Note that when working with an object named C, ++C is more efficient than C++ because C++ must copy the original object in order to return it, whereas ++C just returns the same object (pre-incremented). But with primitives that will fit into a register there is no difference as no copy is actually needed (the result is simply placed in an output register while a working register performs the actual increment).
What does plus plus stand for in computer programming?
++ is an operator that increments the operand. The value of the operand in the expression is incremented first if the ++ is before the operand. The value of the operand in the expression is the same value if the ++ is after the operand.
In c plus plus does the function name is its operand and the parentheses that follow the names are its operator?
No. (Your question not really makes sense, but the answer is clear: no)
What is operand difference between operand and operator?
Simply defining, in an expression like A+B A is an Operand B is an Operand Plus is the Operator in between
What is plus operator is it unary or binary?

How c plus plus get its name?
In the C language, the ++ operator increments the operand. Thus C++ is a shortcut that means C = C + 1. Thus C++ literally means the successor to C.C++ was originally named C with Classes in 1979. It was renamed in 1983.
In Excel the plus sign is an example of an operand in a worksheet formula?
The plus sign is an operator, not an operand. An operand is something that an operator operates on. For example, A3 and 10 are the operands in the following formula and the operator is the plus sign. =A3+10
What is the difference between prefix and postfix increment operator in c plus plus?
Both the prefix and the postfix increment operators increment the operand. The difference is what is the value of the expression during the evaluation of the expression. In the prefix form, the value is already incremented. In the postfix form, it is not. int a = 1; int b = ++a; // both a and b are now equal to 2 int a = 1; int b = a++; // a is equal to 2 and b is equal to 1

What represents the left hand side of a binary operator in c plus plus?
The left hand operand of a binary operator must represent a modifiable lvalue: void f (const int x, int y) { x = y; // error -- x is constant lvalue y = x; // ok }
What is b plus b plus b plus c plus c plus c plus c?
b+b+b+c+c+c+c =3b+4c
What is c plus c plus 2c plus c plus c equal?
c + c + 2c + c + c = 6c
B plus b plus b plus c plus c plus c plus c equals?
b + b + b + c + c + c + c = 3b + 4c
