Question

What is a control flow graph and why is it important for decompilers?

a.

A graph that represents the internal flow of a single procedure

b.

A graph that represents the external flow of a single procedure

c.

A graph that represents the entire program’s flow

d.

A graph that represents the memory flow of a single procedure

Posted under Reverse Engineering

Answer: (a).A graph that represents the internal flow of a single procedure Explanation:Control flow graphs represent the internal flow of a single procedure and are important for decompilers because they can easily be converted to high-level language control flow constructs such as loops and various types of branches.
