That is called Assembly. Or Assembler. (Depends what you read or who you ask lol)
The file extension is .asm
Languages like C compile down to assembly first before being coverted to a .HEX file. (The Hex file being the data written to the chip)
(you'll notice i also provide the .HEX file so if you had a 628A, you could burn that straight to your chip)
C and other lanuages are almost like a "short hand".
Every line of code can be converted to assembly (and does when compiled). But assembly can be heavily condesed by using another languages.
Lets try somethings....
I dont know any other language so I cann't give you an example....
So somebody, please help me out haha....
For those that know assembly AND C, give an example of a snippet of code in each that achieve the same thing.
for example an "If" statement....
