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) {
//declaramos una matriz de punteros de funciones (void)fc(void)
void(*fsm[4])(void) = {state_init,state_load,state_execute,state_exit};
for (int i = 0;i<3;i++){
    fsm[start]();
    printf("\n");
    start++;
    if (start==4) start=0;
}
}

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