Question

I want to initialize an array of size 5 pointers that holds pointers to functions that have no parameters and which returns an int (could be any function that facilitate these requirements).

This is what i tried thus far but i get a syntax error:

int (*func)() fparr[5] = int (*func)();

What is wrong with this syntax?

Answer 1

If the function you want to supply as the default contents of the array is called func, then

1. you better use a typedef,
2. you have to use an array initializer

Consider:

typedef int (*IntFunc)(void);
IntFunc fparr[5] = { func, func, func, func, func };

Or the less readable way, if you prefer to avoid typedef:

int (*fparr[5])(void) = { func, func, func, func, func };
