Feb 8, 2021 · In Python, I know I could just create an array of function names, index into it with the selected option, and then call the function. How would I implement this in C? Or is it even possible? You can create an array of pointers to functions. – …

Function Dispatch Tables in C. One of the most powerful concepts in programming is branching, which most new programmers learn as If-Else statements. This approachable logic flow makes it easy to navigate choices and is present in nearly every codebase out there.

Oct 31, 2008 · How should I use array of function pointers in C? How can I initialize them? A good example is here: (Array of Function pointers), and here is function pointer syntax in detail. int result; int i, j, op; p[0] = sum; /* address of sum() */ p[1] = subtract; /* address of subtract() */ p[2] = mul; /* address of mul() */

Aug 4, 2010 · Then, in lieu of (c - 'A'), write a function/macro that will take as input an ASCII character that you support, and return as output an index number (sort of like a mini hash function). You'd probably want to handle illegal character input, too.

Learn about lookup tables in C programming, how to create and utilize them for efficient data management and retrieval.

That's essentially what a lookup table does in programming – it's a data structure that replaces runtime computations with a simpler array indexing operation. Now, let's explore this concept through some practical examples.

Oct 29, 2023 · Function pointers in C are pointers that can store the address of a function. They allow you to treat functions as data, enabling you to call functions indirectly, pass functions as...

May 1, 1999 · Jump tables, also called branch tables, are an efficient means of handling similar events in software. Here's a look at the use of arrays of function pointers in C/C++ as jump tables.
