Help with grep script

Hello, i am in need of assistance with a linux homework.

1. The problem statement, all variables and given/known data:
I must print out all the lines which have an uneven number of characters([number of characters on line]%2=1)

2. Relevant commands, code, scripts, algorithms:
GREP


3. The attempts at a solution (include all code and scripts):

I have read most of the manual and still not able to come up with a solution to count characters using grep. Very important: using grep is a must.

4. Complete Name of School (University), City (State), Country, Name of Professor, and Course Number (Link to Course):
Universitatea Babes Bolyai Facultatea de Matematica si Informatica, Cluj-Napoca,Romania,Dr. Boian Florian(the course is in Romanian, so i figure it's useless to post a link here)

Note: Without school/professor/course information, you will be banned if you post here! You must complete the entire template (not just parts of it).

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME
zgrep - search possibly compressed files for a regular expression SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename... DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code: (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep. If the GREP environment variable is set, zgrep uses it as the grep program to be invoked. EXIT CODE
2 - An option that is not supported was specified. AUTHOR
