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"); }

typedef void (*sm_tabletype) (void);
sm_tabletype sm_table[] = {state_init, state_load, state_execute, state_exit};

// Your logic here
void run_state_sequence(int start) {
    // Implement using function pointer array
    for (int i = 0; i<3; i++)
    {
        sm_table[((start+i)%4)]();
    }
}

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