Is there an explanation anywhere about why with the inline keyword the execution was slower?
Here are the times
0.02295 //without inline
0.024281 //with inline

Same here. There was no real difference upon adding the inline keyword.

Mine didn’t work at all. Codecademy showed that I completed the exercise and I was able to click the next button (to move on) but with inline nothing happened! Does anyone know why?

Thanks!

Same problem as anaya99 has. It shows that I completed the exercise and I am able to click the next button but nothing happens.

Go back to main.cpp and hit run again

I got 0.02786 ms without inline, and 0.024231 ms with inline. Unlike what earlier posters got, my code actually ran faster.

What is supposed to be the reason behind why using inline functions can either increase or decrease runtime? What is the speeding up or slowing down dependent upon?

There’s always minor differences in the times for either version (with or without inline), for me at least.
Kinda defeats the purpose of the exercise, but the idea is that sometimes using inline will make things faster and sometimes make things slower. I don’t know why as of know (there’s probably a ton of info out there on it) but for code this short and simple it doesn’t make a discernible difference. One we start making more complex stuff there will likely be a difference.
