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 (*state[4])(void);
// Your logic here
void run_state_sequence(int start) {
    // Implement using function pointer array
    for(int i = 0; i < 3;i++)
    {
        state[(i+start)%4]();
        if(i!=2)
        {
            printf("\n");
        }

    }
}

int main() {
    int start;
    scanf("%d", &start);
    state[0] = state_init;
    state[1] = state_load;
    state[2] = state_execute;
    state[3] = state_exit;
    run_state_sequence(start);
    return 0;
}
