structs

[john tindell]

#include <iostream.h>

struct database
{
	int USER_ID;
};
int main()

{
	database users;
	users.USER_ID=110;
		cout<<users.USER_ID;
	return 0;
}

heres my code, now this out puts 110, but when ui change users.USER_ID to 0110 it outputs 72????

im news to c++ so forgive me for the stupid question

Thanks
