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) {
    int i=0;
    void (*arr[4])(void) = {state_init,state_load,state_execute,state_exit};
    while(i<3){
        arr[start]();
        printf("\n");
        // printf("%d\n",start);
        start++;
        if(start==4) start=0;
        i++;
    }
    // Implement using function pointer array
}

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