State Machine Using Function Pointers

declare function pointer and wrap around by modulo %

#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
    char i ;
    int copy ;
    void (*func[4])() = {state_init, state_load, state_execute, state_exit};
    for(i = 0; i<3 ; i++){
        copy = (start+i) % 4;   
        func[copy]();
        putchar('\n');
    }
}

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

Solving Approach

declare     void (*func[4])() = {state_init, state_load, state_execute, state_exit};

and wrap around using (start + i ) % 4; // as 4 elements
