C :

#include<stdio.h>
#include<stdlib.h>
int main()
{
  int n;
  char *a= "I love China!";
  scanf("%d",&n);
  a=a+n;
  while(*a!='\0')
  {
    printf("%c",*a);
    a++;
  }
  printf("\n");
}

C++ :

#include <stdio.h>
int main() {
	char * a = "I love China!";
	int n;
	scanf("%d", &n);
	a = a + n;
	printf("%s\n", a);
	return 0;
}

Java :

import java.util.Scanner;

public class Main {
   public static void main(String[] args) {
	   Scanner s = new Scanner(System.in) ;
	   String str = "I love China!" ;
	   int n = s.nextInt() ;
	   System.out.println(str.substring(n));
	 
   }
}
