Unable to run apache on xampp

[rachana90]

Am finding error when trying to run the apache as below:
02:18:45 PM [Apache] Error: Apache shutdown unexpectedly.
02:18:45 PM [Apache] This may be due to a blocked port, missing dependencies,
02:18:45 PM [Apache] improper privileges, a crash, or a shutdown by another method.
02:18:45 PM [Apache] Press the Logs button to view error logs and check
02:18:45 PM [Apache] the Windows Event Viewer for more clues
02:18:45 PM [Apache] If you need more help, copy and post this
02:18:45 PM [Apache] entire log window on the forums


I have tried changing the port number listen as 8022 and localhost as 8022. Please help me in resolving the issue. Thanks in advance.
