State Machine Using Function Pointers

Code

#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 (*state[4])()={ state_init, state_load, state_execute, state_exit };

   int index = start;
    for (int i = 0; i < 3; i++) {
        state[index]();        
        index = (index + 1) % 4;  
    }
}

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