What are jump tables in programming?
Jump tables are data structures used to optimize the selection of code paths, often in switch-case statements.
How do they improve performance compared to if-else statements?
They allow for constant-time access to code paths, reducing the number of comparisons needed, which speeds up execution.
Can you give me an example of how a jump table is implemented?
Sure! In C, a jump table can be implemented using an array of function pointers that correspond to case labels.
Are there any downsides to using jump tables?
Yes, they can increase memory usage and may not be suitable for small numbers of cases due to overhead.
