Set breakpoints at various places in a C++ program ‘star.cc’ using gdb (GNU Debugger). The program star.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 star.cc from examples/tcp to scratch
2. Configure and build ns-3.
3. Execute command: ./waf shell
4. Execute command: gdb build/scratch/star
5. Set breakpoints at line numbers 50, 70 and 80.
6. List all breakpoints.
7. Delete all breakpoints.
8. List all breakpoints again. (Expected output: No breakpoints or watchpoints)

Provide the snapshots at each step for evaluation of the completed task.
