Question

What is the most efficient approach to implement large switch blocks?

a.

Use a tree implementation

b.

Use an array implementation

c.

Use a pointer table implementation

d.

Use a function call implementation

Posted under Reverse Engineering

Answer: (c).Use a pointer table implementation Explanation:The most efficient approach (from a runtime performance standpoint) for large switch blocks is to generate a pointer table. The idea is to compile each of the code blocks in the switch statement, and to record the pointers to each one of those code blocks in a table.
