State Machine Using Function Pointers

Code

#include <stdio.h>

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

// Your logic here
void run_state_sequence(int start) {
    // Implement using function pointer array
    void (*func_arr[4])();
    func_arr[0] = state_init;
    func_arr[1] = state_load;
    func_arr[2] = state_execute;
    func_arr[3] = state_exit;
    for (int i = 0; i < 3; i++){
        func_arr[(start + i) % 4]();
    }
}

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