Caleb, Dude you are a lifesaver. I'm taking my first Introduction to Problem Solving and Algorithm Design with UMUC and I was completely lost with what the professor was trying to say. I think he just expected all of use to know it. Thanks again so much and I'm hooked on your videos.

[Misty-Die-Hard]

This right here is going to help me achieve my dream of being a game designer. I'm so glad YouTube has so many talented people that can teach me the things I've never known I could learn.

Excellent video and THANK YOU. Only one thing I would add and that is that people might not know that a "file" named "a.out" was created. I'm saying that because you only showed how to run the program that got created by the compiler but not where or what was created. Some folks may not know what you were doing when you showed "./a.out". For example maybe show how to do an "ls" command to show that the program file got created. Sounds silly and I may be a little nit picky but I just know how it is when I'm learning something. EXCELLENT video.

This is exactly what I’ve been looking for! I just started dabbling in Ubuntu and wanting to start learning C programing. The the short videos with accessible information are excellent!

Due to the lack of c program tutorials in my country I ended up here, and it turned out to be an amazing tutorialThank you

[usmani_ferdows]

I appreciate it Dude, I am new in C Programming, your videos are really great.

[TakeElite]

for my fellows who want to follows this, this video is incomplete :
you have to type in vim
esc
:w ( for saving )
:q
call the file with this command
Gcc hello.c ( nothing happened )
write : ./a.out
hello the world

Your video popped up on my feed. Seems it's a nice playlist for beginners. You might explain later but jumping from compiling with gcc to running the output might make people confused. You could have listed the content of the directory (sorry, you are on mac, folder) and explained that if you dont specify the output name cgg will outomatically name the output that.

4:17 in windows, it'd be (1) or, taking from the vscodium, to put the desired name of .exe right there: (2) where -o stands for output i guess.
"gcc.exe hello.c"
"gcc.exe hello.c -o hello.exe"

[TanjoGalbi]

Rather than allow gcc to create a.out as a default output which can be confusing when you have multiple .c files it's better to specify the output to give it a more meaningful name:

gcc -o hello hello.c

This will create a hello file which is then run like this:

./hello

[SuperJSM]

Instead of the classic "Hello World!" I put in "ki pugu othu" which in a language (not programming language) I'm developing directly translates to "Hello World!"

Man programming is fun!

[siddhibhosale]

caleb, you are just amazing! I CAN UNDERSTOOD ALL THIS ONLY BECAUSE OF YOU...

[larrybland]

excellent tutorial. i am using these tutorials as stepping stones to becoming a software engineer in Sunnyvale California

[paullawrence]

Why does the "./a.out" command give " No such file directory found" error? Help?

[ZaykaRyRo]

What a great channel!! Absolutely enjoying it.

[annoyingprecision]

Thanks a ton for these magnificent tutorials. Strangely, Vim is very addictive and gratifying. :)
