This should do what you want, I think:

	typedef char name_type[20];

	typedef struct person {
		name_type name;
		int age;
	} person;

	main()
	{
		person p;

		strcpy(p.name, "Joe Schmoe");
		p.age = 12;
	}

It sounds like you are a Pascal person who is new to C.  The switching
of types and variable names confused me for a long time especially when
typedefing structs.  Often you will see people just use a struct template
without actually defining any variables, and this is also confusing.
