Question

How is the meaning of the conditional jump reversed in single-branch conditionals?

a.

By changing the order of the operands in the TEST instruction.

b.

By adding a NOT operator to the condition.

c.

By using a different conditional jump instruction.

d.

By reversing the condition in the source code.

Posted under Reverse Engineering

Answer: (d).By reversing the condition in the source code. Explanation:In single-branch conditionals, the meaning of the conditional jump is reversed by reversing the condition in the source code. For example, if the source code checks whether a variable is equal to zero, the assembly language code will check whether the variable is non-zero (since it will jump to the code that follows if the variable is zero).
