I did some poking around and I can't seem to find a way to get ints and floats printing to debug window. I'm on Day 9 and wanted to see the stream of values of the sine wave over time. I tried printf but I have no idea where it is outputting, and I'm on the verge of diving into a massive rabbithole of debug error tracking - this should be a really simple solution that someone here must know.
Thanks again!
Thanks again!
You need to convert float/int values to string and then use OutputDebugString to print this string. To convert them to string there are multiple options to do that:
1) Write your own function to do that
2) Use some open source code, for example this: https://github.com/weiss/c99-snprintf/blob/master/snprintf.c
3) Depend on C runtime and use sprintf/snprintf function (from <stdio.h> header). Casey shows how to do this in Day 10 at 32:26 mark.

Decidedly less "handmade" but, if you don't mind that, you could use cppformat.
Here is a simple test main:

Awesome guys, I'll check these out, thank you!
