Professional trainer here, and your videos on C are really amazing. You have covered all the features of C language in a very succinct manner.

I just found the program below and I'm trying to figure out why there is no int keyword between register and a? And why the return says -1 and not 0 as always? int main() { register a = 80; auto int b; b = a; printf("%d ",a); printf("%d",b); return -1; }

[@PortfolioCourses]

Great questions! 🙂 If no type is provided, some compilers will default the type to int, but it depends on the compiler: stackoverflow.com/a/11064331. And returning 0 from a main function will have the program exit with a 'success' status, returning -1 will have the program exit with an 'error' status so it is a bit unusual to see it used here as the return value.

@@PortfolioCourses Can you please explain how we choose return 0 and return -1

Is this course like the 6 hours one i just watched?

[@PortfolioCourses]

Great question Jay! In these videos in the C Programming Tutorial playlist, I go into more detail on some of the same topics covered in the 6 hour course. So there will be a lot of overlap with the full course, but we'll go deeper into the different concepts too. 🙂

[@jayjenous7601]

I thought so, i'll keep watching till the end
