Hi
I'm still learning C but, I noticed that q, w, e, r are declared as double, but in scanf you’re using %d which is for integers. That might cause problems when running the code.
I tried it with %lf instead, and it worked correctly. 👍

Hi,
I am also learning C programming. The thing you will notice is that the q,w,e,r are declared as doubles, but I used scanf which is an integer. The reason I use this is because I will type the value of the q,w,e,r as an integer.
Thank you.

Got it 👍 Makes sense. But maybe it’s clearer to just declare q, w, e, r as int (and use an int sum too), instead of doubles with %d. Thanks for explaining tho 😅.
