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 (*pp[])() = {state_init, state_load, state_execute, state_exit }; 
void run_state_sequence(int start) {
    for(int i = start; i <= (start + 2); i++){
        pp[i%4](); 
        printf("\n");
    }
}

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