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) {
    // Implement using function pointer array
    void (*state_pointer_func[4])() = { state_init, state_load, state_execute,state_exit};
    int i = start,n=0;
    while(n<3){
        state_pointer_func[i]();
        printf("\n");
        
        if(i==3){
            i = -1;
        }
        i++;
        n++;
    }
        

}

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