Solution:

Toad only works with Oracle11g client-32 bit on Windows 10- 64 bit or any version of windows,in my case it was windows 10-64bit.

firstly i was installed Oracle11g client 64bit on Windows 64 bit and was getting error as above mentioned then
de installed and installed 11gclient-32bit on Windows-64 bit,after that toad is working fine.
