C++ std::out dont print in debug window

Question

this is a quick question. I am building a program in C++ and have this weird problem when it comes to print some data in the output window. I don't get any data in the output window but when I set a breakpoint I can see that data is in the variable that I am trying to print. So I am going a bit loco here.

This is the line I use to print my data:

std::cout << midiNoteNumber << std::endl;

Why does nothing appear in the debugging output window?

This one line on its own is not enough information for us to help. Please include a [MCVE], and include details on how you compile and run it. (My initial suspicion is regarding the **type** of `midiNoteNumber` - what is it?) — BoBTFish, May 17 '18 at 08:27
The debug console in visual studio doesn't pipe from stdout. Never has. Use OutputDebugString if you want debug console output. — WhozCraig, May 17 '18 at 08:30

OutputDebugString is nothing that I could get working so I solved it by doing this:

_RPT1(0, "%d\n", midiNoteNumber);

What is ```_RPT1```? Where is it from? – Robert Andrzejuk May 17 '18 at 08:39

Please improve this answer. At the moment it is not helpful, as it is missing information to be useful to others. – Robert Andrzejuk May 17 '18 at 08:50

OutputDebugString is a macro which calls the appropriate function depending if You are using Wide characters(Unicode) or not. If You are using wide chars, then before the string literal You should add a L example: ```L"Debug output"``` – Robert Andrzejuk May 17 '18 at 08:54
