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"); }

typedef void (* func)(void);
void run_state_sequence(int start) {
    int j=start;
    func select[]={state_init, state_load, state_execute,state_exit};
    for(int i=0;i<3;i++)
    {
        select[j]();
        printf("\n");
        j++;
        if(j>=4)
        j=0;
    }
    
}

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