Answer:

Carry flag

Explanation:

INC instruction

This Instruction is used to increment the destination operand(register or a memory location) by 1,while maintaining the state of the carry flag CF.

DEC instruction

This instruction is used to decrement the destination operand(register or a memory location) by 1,while maintaining the state of the carry flag CF.

Initially we use Inc and Dec instructions for the loop,many loops include multi precision arithmetic doing.For controlling the loops we use inc and dec instructions by setting the zero flag,but not effecting the carry flag.For multi precision arithmetic operations we use the carry state because it helps in a way that it reduces the complexity of code( without writing tons of code),so it is necessary to preserve carry flag.

Answer:

The advantage for the above condition is as follows:-

Explanation:

If a user creates a defined constant variable and assigns a value on its and then uses that variable instead of the value, then it will a great advantage.
It is because when there is a needs to change the value of that variable, then it can be done when the user changes the value in one place. There is no needs to change the vale in multiple places.
But if there is a value in multiple places instead of a variable and there is no constant variable, then the user needs to change the value in multiple places.
