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 (*state_machine[5])() = {state_init,state_load,state_execute,state_exit};
     int reset = 3;
     while(reset){
       start =  (start >= 4) ? 0 : start;
       state_machine[start++]();
       reset--;
       printf("\n");
     }


}

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