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) {
    // Implement using function pointer array
    void(*states[])() = {state_init, state_load, state_execute, state_exit};
    int count  = 3;
    for(int i =start; i < 4; i++) {
        count--;
        states[i]();
        printf("\n");
        if (count == 0) {
            return;
        }
    }
    for(int i =0; i < start;i++) {
        count--;
        states[i]();
        printf("\n");
        if (count == 0) {
            return;
        }
    }

}

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