State Machine Using Function Pointers

Code

#include <stdio.h>

void state_init()    { printf("Init"); }//0
void state_load()    { printf("Load"); }//1
void state_execute() { printf("Execute"); }//2
void state_exit()    { printf("Exit"); }//3

// Your logic here
void run_state_sequence(int start) {
        
         void(*fn[4])(void)={state_init,state_load,state_execute,state_exit};
        for(int i=0;i<3;i++)
        {
            int j =(start+i)%4;
            fn[j]();
            printf("\n");
            }


}

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