I understand I can use pointers for functions.
Can someone explain why one would use them, and how? Short example code would be very helpful to me.

I'm looking for a way to automatically (as part of the compilation/build process) generate a "table" of function pointers in C.
Specifically, I want to generate an array of structures something like:
typedef struct {
void (*p_func)(void);
char * funcName;
} funcRecord;
/* Automatically generate…

I have a function which takes a block of data and the size of the block and a function pointer as argument. Then it iterates over the data and performes a calculation on each element of the data block.
The following is the essential outline of what I am doing:
int myfunction(int* data, int size…

How does C++ handle function pointers in relation to functions with defaulted parameters?
If I have:
void foo(int i, float f = 0.0f);
void bar(int i, float f);
void (*func_ptr1)(int);
void (*func_ptr2)(int, float);
void (*func_ptr3)(int, float = 10.0f);
Which function pointers can I use in…

I'm doing a linear genetic programming project, where programs are bred and evolved by means of natural evolution mechanisms. Their "DNA" is basically a container (I've used arrays and vectors successfully) which contain function pointers to a set of functions available.
Now, for simple problems…
