Question

I want to make a function pointer array and be able to call them in a for-loop. How can I achieve this? I have tried:

void (**a) (int);
a[0] = &my_func1;
a[1] = &my_func2;
a[2] = &my_func3;

for ( i = 0; i < 3; i++){
    a[0]();
    (*a[0])(); // Neither does work
}

But I am missing some syntax I guess:

error: too few arguments to function ‘*(a + (long unsigned int)((long unsigned int)i * 8ul))’

Answer 1

I guess the below code is what you need.

typedef void * func_pointer(int);

func_pointer fparr[10];

for(int i = 0; i<10; i++)
{
     fparr[i](arg); //pass the integer argument here
}
