Function pointers

• In C, if you care to be consistent with your switch statements, consider using function pointers instead.
• Instead of having a switch where 4 different events can happen, make 4 different functions and a function pointer

void event0(void);
void event1(void);
void event2(void);
void event3(void);

void (*function_array[4])(void);

function_array[0] = &event0;
function_array[1] = &event1;
function_array[2] = &event2;
function_array[3] = &event3;

function_array[2](); // calls event 2 function

int n = 2;

switch(n){
    case 0;
        event0();
    case 1;
        event1();
    case 2;
        event2();
    case 3;
        event3();
}

// can now be performed with:

function_array[n]();
