I've created a simple database using Oracle SQL (iSQL plus). How can I print the table structure and its contents?

Two different queries will be used for this. The table to show the table structure is:
describe <table_name>
;
or
describe table <table_name>
;

I know the desc
command:
http://www.riteshmandal.com/oracle.htm
DESC or DESCRIBE : Used to describe the table structure present in the tablespace.
USE : DESC e.g. DESC Employee;
USE : SELECT * FROM to view all the data inside the table. e.g. SELECT * FROM Employee
Example:
SQL> -- create demo table
SQL> create table Employee(
2 ID VARCHAR2(4 BYTE) NOT NULL,
3 First_Name VARCHAR2(10 BYTE),
4 Last_Name VARCHAR2(10 BYTE),
5 Start_Date DATE,
6 End_Date DATE,
7 Salary Number(8,2),
8 City VARCHAR2(10 BYTE),
9 Description VARCHAR2(15 BYTE)
10 )
11 /
Table created.
SQL>
SQL> desc Employee;
Name Null? Type
-------------------------------------------
ID NOT NULL VARCHAR2(4)
FIRST_NAME VARCHAR2(10)
LAST_NAME VARCHAR2(10)
START_DATE DATE
END_DATE DATE
SALARY NUMBER(8,2)
CITY VARCHAR2(10)
DESCRIPTION VARCHAR2(15)
SQL>
SQL>
SQL>
SQL> -- clean the table
SQL> drop table Employee
2 /
Table dropped.
