57. State Machine Using Function Pointers

#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(*fptr[])() = {{state_init},{state_load} ,{state_execute} ,{state_exit}};
int i = start;
int count =0;
while((i <= (start+2))&& (count < 3)){
    if(i>3){
        i=0;
    }
    fptr[i]();
    i++;
    count++;

}
    

}

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