You attempt to query the data base with this command:
SELECT name, salary FROM employee WHERE salary=(SELECT
salary FROM employee WHERE last name='Wagner' OR dept no=233)

Choose most appropriate option from the following:
1)Sub-queries are not allowed in the where clause.
2)a multiple row sub-query used with a single row comparison
operator.
3)a single row query is used with a multiple row comparison
operator.

to return more than single rows as resultset as OR condition
is used so 3rd option is likely to be occured.

This program numbers the lines found in a text file. Write a program that reads text from a file and outputs each line preceded by a line number. Print the line number right-adjusted in a field of 3 spaces. Follow the line number with a colon, then one space, then the text of the line. You should get a character at a time and write code to ignore leading blanks on each line. You may assume that the lines are short enough to fit within a line on the screen. Otherwise, allow default printer or screen output behavior if the line is too long (i.e., wrap or truncate). A somewhat harder version determines the number of spaces needed in the field for the line numbers by counting lines before processing the lines of the file. This version of the program should insert a new line after the last complete word that will fit within a 72-character line.
