++ 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.

Simply defining, in an expression like A+B

A is an Operand

B is an Operand

Plus is the Operator in between

Subtract with borrow.Subtracts source operand and borrow flag from destination operand.

Yes, both operand 1 and operand 2 can be in memory in the 8086. An example is the string copy primative, which takes source and destination operands to be memory pointed to by DS and ES.

op code is used as the value of instruction . And operand is address location where the instruction can meet.

No, a unary expression consists of one operand and one operator

// a very simple calculator


if(isset($_GET['value1']))
{
$val1 = $_GET['value1'];
$val2 = $_GET['value2'];
$operand = $_GET['operand'];
eval('$result=' . $val1 . $operand . $val2);
?>Result: }


?>

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

[1] the accumulator is meant to be an operand. so there is no requirement for the operand address field for one operand in the instruction. this results in short of CPU supports zero address instructions. Normally CPUs have two types of instructions:

1)zero address
2)single address

the single address instruction have one operand in main memory and the other in accumulator.

[2] instruction cycle takes less time. it saves time in instruction fetching due to the absence of operand fetching due to the absence of operand fetch.

The possible states that define an instruction execution are as follows:

Instruction address calculation - Determine the address of the next instruction to be executed.

Instruction fetch - Read instruction from its memory location into the processor.

Instruction operation decoding - Analyze instruction to determine type of operation to be performed and operand to be used.

Operand address calculation - If the operation involves reference to an operand in memory or available via I/O, then determine the address of the operand.

Operand fetch - Fetch the operand from memory or read it in from I/O.

Data operation - Perform the operation indicated in the instruction.

Operand store - Write the result into memory or out to I/O.

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.

MP Compares the first source operand with the second source operand and sets the status flags in the EFLAGS register according to the results. The comparison is performed by subtracting the second operand from the first operand and then setting the status flags in the same manner as the SUB instruction. When an immediate value is used as an operand, it is sign-extended to the length of the first operand.

So, only the flags are affected.

Operation:

temp = Source1 - SignExtend(Source2);

ModifyStatusFlags(); //Modify status flags in the same manner as the SUB instruction

Flags affected:

The CF, OF, SF, ZF, AF, and PF flags are set according to the result.

used as implicit operand

Operand data type is one of the two components of computer language and expressions. It is the manipulated object or the instruction that specifies which operation is to be performed.

An opcode is an instruction. An operand is information used by the opcode. Not all opcodes require operands.

In an instruction cycle with indirect addressing, the CPU fetches the instruction, decodes it to determine the memory address of the operand stored in a register, fetches the operand from the memory location pointed to by the register, and executes the instruction using the operand. Finally, the CPU stores the result back in memory if needed. This extra step of fetching the operand based on the indirect memory address adds complexity to the instruction cycle.

1st address for operand.

2nd address for another operand.

3rd address for store the result.

If you are asking in terms of computers then an operation is performed on an operand.

The sizeof() operator returns the number of bytes allocated to the operand.

A mathematical operation operates on an operand - or on an argument.

those which have single operand e.g mov A

linear units only give the magnitude of a operand, they do not specify the direction

Every instruction contains to parts: operation code[opcode],and operand.

The first part of an instruction which specifies the task to be performed by the computer is called opcode.

The second part of the instruction is the data to be operated on.,and it is called operand. The operand[or data]given in the instruction may be in various forms such as 8-bit or 16-bit data, 8-bit or 16-bit address, internal register or a register or memory location.

unary operators like ++,--

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

Yes, a unary operator is an operator that only has one operand. Examples of unary operators are negative (-), positive (+), increment (++), decrement (--), address of (&), dereference (*), logical not (!), sizeof, one's complement (~), new, and delete.

The sizeof operator is used to determine the length of its operand (in bytes). The operand must be a type or an object of a type (a variable). The operator is a constant expression and therefore executes at compile time. As such there is no runtime overhead in repeated use of the sizeof operator.

The address bus is a section of the bus that emits the address of the desired instruction or operand.

The sum is a binary operation. The first operand is increased by the value of the second.

Negative or operation logic is anoperation on one logical value, typically the value of a proposition, that produces a value of true when its operand is false and a value of falsewhen its operand is true. Is this the Definition you were looking for???

We need to find the S.T so we need to find the values of the Symbols!!!

The format of the EQU pseudo-op is : Lable EQU operand, so we need to find the value of the label in order to find the S.T

It is an binary arithmetic operator which returns the remainder of division operation. It can used in both floating-point values and integer values.

opLeft % opRight where, opLeft is the left operand and opRight is the right operand. This expression is equivalent to the expression opLeft - ((int) (opLeft / opRight) * opRight)

byte ptr is an assembler directive that says the following operand is an address of a byte.

The noun forms of the verb to operate are operator, operation, operand, and the gerund, operating.

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.

Depends on your code. Post it, along with your variable declarations.

because the operand is available in the instruction itself

Identity property. Anything multiplied by 1 will give an answer identical to the operand.

Operators that act upon 2 operands are referred to as binary operators.These are distinguished as the left to right operand.
