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 (*func[4])(void);

    func[0] = state_init;
    func[1] = state_load;
    func[2] = state_execute;
    func[3] = state_exit;

    int count=0;
    int i;
    for(i=0;i<3;i++){
        func[(start+i)%4]();
        printf("\n");
        
    }
    
}

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