	       char author[20];
	   };
	    //Structure initialization
	    struct book cpp = {1001,"CPP","ST Anthony"};
	    struct book java;
	    printf("%d : %s : %s\n",cpp.book_no,cpp.book_name,cpp.author);
	    //Assigning values to memebers
	    java.book_no = 1002;
	    strcpy(java.book_name,"Java Programming");
	    strcpy(java.author,"Dennis kumar");
	    printf("%d : %s : %s\n",java.book_no,java.book_name,java.author);
	}
Output 
1001 : CPP : ST Anthony
1002 : Java Programming : Dennis kumar
