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 (*seq[4])() = { state_init, state_load, state_execute, state_exit };
    int index;
    for (int i =0; i<3; i++){

        index = (start + i) % 4;
        seq[index]();
    }
     

}

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