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) {
    void (*myFunc[4])(void) = {&state_init, &state_load, &state_execute, &state_exit};

    for (int i = 0; i < 3; ++i)
    {
        myFunc[(i+start)%4]();
        printf("\n");
    }


}

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