I'm debugging a C++ function in Visual Studio 2019 and there are multiple return statements in it.
I want to know which return statement exited the current function.
Right now I'm adding breakpoints to all the return statements and continuing the execution the execution.
Is there a simpler way.?

Not that I know of.
If the return statements return distinct values, you could put the breakpoint in the calling function and examine the returned value.
Sometimes you can get what you need by placing temporary print statements in front of some or all of the return statements

Hi pasha-mahmood,
As BarrySchwarz and Wayne say, printing statements before return is a general method and should be a simpler way.
If you have any update, please feel free to contact us.

Further to Barry's suggestion to use a print before each return, note that
you can use the predefined macro LINE to display the source code line
number. So code such as:
std::cout << __LINE__ + 1 << '\n';
return n;
will display the source line number of the return statement.
If you don't want to clutter up the stdout display with these line numbers,
or if you don't have a console attached to your program, you can use
OutputDebugString (OutputDebugStringA, OutputDebugStringW) to show the
line numbers in the Output Window of the Debug session.
