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
typedef void (*funptr)();
   funptr ptr[] = {state_init, state_load, state_execute, state_exit};
// void (*funtr[])()
    //we need to exactly loop 4 times
for (int i =0; i < 3 ; ++i)
{
    int current_index = (start + i) % 4;


     ptr[current_index]();
     printf("\n");
}


}

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