Ya,it was asked in an written test..

From the posting rules (http://www.codingforums.com/rules.htm):
1.5) No homework assignments - Do not post your entire homework assignment and request that other members do it for you. This is considered cheating, and your thread may even be used by your school to prove your guilt. Now, you may ask for advice or help on a specific aspect of your assignment that you're having trouble with. Use common sense as far as what's acceptable in terms of soliciting help with homework assignments.

Iam not really asking for readymade code..
All i want is the logic to proceed on it...

Here's the pseudocode:
print {this line of numbers and spaces}
print {this line of numbers and spaces}
print {this line of numbers and spaces}
print {this line of numbers and spaces}
print {this line of numbers and spaces}

:rolleyes:
