57. State Machine Using Function Pointers

#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 (*op[])(void) = {state_init, state_load, state_execute, state_exit};
    for(int i = 0 ; i < 3 ; i++){
        op[(start + i) %4]();
        if(i != 2) printf("\n");
    }

}

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