Answer 1

Answer:

2) Zero Flag (Z)

3) Auxiliary Carry Flag (AC)

4) Parity Flag (P)

5) Carry Flag (CY)

These flags as they name indicates are used to make decisions which are required for looping and branching constructs. These flags get set for integer, character and floating operations.

Answer 2

The ‘flag register’ is primarily used for ‘looping and branching constructs’ is true statement

Explanation:

• ‘Conditional jump instructions’ examine the settings of ‘one or more flags’ in the ‘flag register’ and ‘jump to a destination statement’ or fall through to the next instruction depending on the ‘flag values’.  
• ‘Conditional jump instructions have fast and ‘near-displacement variants’. There is a huge collection of ‘conditional jump instructions’. These are used when ‘statements and loops’, often in ‘conjunction with comparative instructions’, are used to test ‘Boolean conditions’.
