How do I store a function to a variable?

Question

I think they are called functors? (it\'s been a while)

Basically, I want to store a pointer to a function in a variable, so I can specify what function I want to use

Answer 1

unsigned int (* myFuncPointer)(unsigned int) = &func_1;

However, the syntax for function pointers is awful, so it's common to typedef them:

typedef unsigned int (* myFuncPointerType)(unsigned int);
myFuncPointerType fp = &func_1;
