I will run the following script:

#!/bin/bash
./myprogram

#get exit code
exitvalue=$?

#log exit code value to /var/log/messages
logger -s "exit code of my program is " $exitvalue

But I don't want log message to be written in /var/log/messages because I don't have root privileges. Instead I want it to be written to a file in my home directory: /home/myuser/mylog

How should I modify logger command above?

$ man logger

Logger provides a shell command interface to the syslog(3) system log module.

You'll need to change your syslog configuration if you want it to log things to other places. You could establish a certain facility that has an output file in your home directory, for example. You would need to be root to do that, though.

I don't think you really need to (or want to) involve logger/syslog for this. Simply replace the last line of the script with:

echo "Exit code of my program is $exitvalue" >> /some/file/that/you/can/write/to

If you want to use logger so that the message appears both in the system logs and in some file of yours, you might do

  logger -s your message 2>&1 $HOME/somefile

since the -s option to logger also outputs on stderr which is redirected with 2>&1
