Hi @kiranchandramohan, sorry there is some issue with my clang-format configuration in my code editor. 

Just pushed the commit after modifying the ```check-omp-structures.cpp``` using ```git clang-format```. Please let me know if any changes are required. Please submit the patch if everything is fine. Thanks and sorry once again.
