Mac M1 Debugging Step Through help

[jdtaylor311]

Hello everyone,

I'm on the Mac M1 using the C/C++ Extension for building and CodeLLDB for debugging. I know this has instruction level and source level step through. I'm trying to make it to where it's only source level step through. I've tried disabling the disassembly view to see if the instruction Level Step through gets disabled but it does not. The reason I'm wanting to disable this is because I'm wanting to the see the output from printf function in the output console but it doesn't show up until I've stepped through the instruction level after the source level. Any help with how I can do this would be appreciated.

Thank you!

Can you simply set a breakpoint after printf?

Hey @vadimcn, Thank you for the quick reply. So it's kind of weird now. It's like it's one line behind on the step-through from where it should be. So I put these lines in the code...
printf("%d ", A[i]);
printf("\n");
When stepping through this in a simple for loop, it prints the first line after I step over the second line.
Is this normal behavior?

It seems when replacing the printf with cout <<, the step over functionality works great but the printf is lagged behind and typically requires me to step into instructions before it outputs to terminal.

Stdout is typically line-buffered, so your output gets sent to the terminal only after you write \n.

Thank you so much for that! New to c and c++ so I didn't know that little nuance!
