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"); }

void (*func_ptr[4])() ={state_init, state_load, state_execute, state_exit};
// Your logic here
void run_state_sequence(int start) {
    // Implement using function pointer array
    for (int i = start; i <= start + 2; i++){
        (*func_ptr[(i%4)])();
        printf("\n");
    }
}

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