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) {
    void (*farr[])(void) = {state_init,state_load,state_execute,state_exit};
    int j = start;
    for (int i=0;i<3;i++){
        // j=start;
        farr[j]();
        printf("\n");
        // j++;
        if(j>=3){
            j=0;
        }
        else{
            j++;
        }
    }

}

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