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 (*bootup_states[][3])(void){
        {state_init,state_load,state_execute},
        {state_load,state_execute,state_exit},
        {state_execute,state_exit,state_init},
        {state_exit,state_init,state_load},
    };
    for(int i = 0;i<3;i++){
        bootup_states[start][i]();
        printf("\n");
    }
}

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