I compiled a c++ file in Unix as gcc filename.cc. It didn't give me any error. But when I type a.out next it is saying file not found or bad command. The same thing is happening when I try to compile and run a C file giving the command cc filename.c and a.out.

Kindly help me.

Try this:

/a.out

My guess is that you're logged in as root and the default PATH for root is NOT to include the current directory or ".".  By saying ./<program_name> you're telling the shell to run the a.out in the current working directory.

You can also compile with the -o option like this:

gcc filename.c -o filename

so the output will go to filename instead of to a.out.
