Print the data types of variables used in a C++ program ‘tcp-bulk-send.cc’ using gdb (GNU Debugger). The program tcp-bulk-send.cc can be found in examples/tcp. Copy this program in scratch folder and follow the steps given below to start debugging a program using gdb in ns-3:

1. Copy tcp-bulk-send.cc from examples/tcp to scratch
2. Configure and build ns-3.
3. Execute command: ./waf shell
4. Execute command: gdb build/scratch/tcp-bulk-send
