structure printing

I'm trying to declare, initialize, and print the contents of a structure. The last printf attempts to print a structure within a structure. Is my info initialized properly and will it print properly?

Struct customer 
	{
	int account;
	char street[60];
	char citystate[20];
	int zip;
	float balance;
	int creditlimit;
	struct customer * account;
	};
 
Struct customer = {
	3303101122,
	"Jones Street",
	"Springfield MA",
	01104,
	5310.51,
	int 10000,
	struct customer * account = 0
	};
 
printf("\n",customer.account);
printf("\n", customer.street);
printf("\n", customer.citystate);
printf("\n", customer.zip);
printf("\n", customer.balance);
printf("\n", customer.creditlimit);
printf("\n", &customer[6]);

printf() has format specifiers for basic data types, but those do NOT include structures.

For example, you can print:

%s - string / const char array / const char *
%d - integer
%f - float
%c - single character

See below, I have modified your statements with specifiers according to the data types you declared. However, to print an array of structs or nested structs, you must write a routine to print each member, can't print the whole thing.

printf("%d\n",customer.account);
printf("%s\n", customer.street);
printf("%s\n", customer.citystate);
printf("%d\n", customer.zip);
printf("%f\n", customer.balance);
printf("%d\n", customer.creditlimit);
// printf("\n", &customer[6]); // ILLEGAL, CANT PRINT A STRUCT OR ARRAY OF STRUCTS

Also, a suggestion based on experience.

Use strings / char arrays for zipcode. Leading zeros will be preserved with a string, but not with a plain int.

Same goes for account code, if your accounts may have leading zeroes, then you will lose them unless using strings.

Also printf supports multiple variables in the format.

printf("%d\n%s\n", customer.account, customer.street);
