Data breakpoint of Visual Studio

Reading "Art of software debugging" at home in the evening, I found that the gdb monitoring point (watchpoint) is very useful, so I wanted to see if Visual Studio has corresponding functions. After a rough search, we found that the corresponding function of Visual Studio should be a data breakpoint. FirstProgramSet a breakpoint at the entrance, and then press F5 to start debugging. When the program is paused at the breakpoint, click "new"-> "new" in the Breakpoints window.
Data breakpoint... ", for example:

 

 

Unfortunately, Visual Studio can only monitor changes in variables or memory locations, but cannot monitor changes in expressions. The function is weaker than GDB. Watch in Visual Studio is not the same as watchpoint in GDB. I wonder if vs2012 has any improvement in this regard.
