State Machine Using Function Pointers

Code

#include <stdio.h>

void state_init()    { printf("Init"); }
void state_load()    { printf("Load"); }
void state_execute() { printf("Execute"); }
void state_exit()    { printf("Exit"); }

// Your logic here
void run_state_sequence(int start) {
    // Implement using function pointer array
    void (*func_ptr1)(void) = &state_init;
    void (*func_ptr2)(void) = &state_load;
    void (*func_ptr3)(void) = &state_execute;
    void (*func_ptr4)(void) = &state_exit;

    void (*func[4])(void) = {func_ptr1,func_ptr2,func_ptr3,func_ptr4};
    int size = 4;
    int count = 0;
    while(count < 3){
        func[(start + count) % size]();
        printf("\n");
        count++;
    } 
}

int main() {
    int start;
    scanf("%d", &start);
    run_state_sequence(start);
    return 0;
}
