Hi Akshat, > -i really dont have a clue to what tool chain driver means.sorry for that. A "tool chain driver" is a program that executes other programs, in the proper order, to achieve a particular goal. For example, the gcc tool chain driver runs the preprocessor, then takes the output from the preprocessor and runs that output through the compiler, then takes that output from the compiler and runs it through the assembler, then takes that output from the assembler and runs it through the linker, to produce the executable. > for the following simple code i thought its obvious that 'hello' is printed > but that doesnt happen. > as far as i knew the code is executed sequentially. You have not flushed your buffer yet, so the "Hello" is languishing in the buffer. Add a ... cout.flush(); ... statement to flush the buffer, before entering the loop. HTH, --Eljay
