Hello
          Thank you for your patience.
          And i run 3 steps:
          1.copy mytx.cpp to the uhd/host/example
          2.change the CMakeLists.txt on the uhd/host/example,and just:
SET(example_sources
    benchmark_rate.cpp
    network_relay.cpp
    rx_multi_samples.cpp
    rx_samples_to_file.cpp
    rx_samples_to_udp.cpp
    rx_timed_samples.cpp
    test_dboard_coercion.cpp
    test_messages.cpp
    test_pps_input.cpp
    test_timed_commands.cpp
    transport_hammer.cpp
    tx_bursts.cpp
    tx_samples_from_file.cpp
    tx_timed_samples.cpp
    tx_waveforms.cpp
    txrx_loopback_to_file.cpp
    latency_test.cpp
    fpgpio.cpp
    mytx.cpp
)
       3. cd build
           cmake ..
           make
   This is right?

Another question:
           If i just write a cpp,what is the most convenient to run my .cpp document?To do something like up examples or by other ways?
Thank you very much.You help me a lot.
Best regards

Glad we could help, but you're really asking questions about compiling, code management, and cmake, which are not specific to GNU Radio. If someone here can help you and has the time to, great, but there's a ton of resources on the internet to help you understand these things.
