Detailed explanation of "hello, world" in C?
I am trying to print "hello, world" on screen in in C using this code:
#include <stdio.h>
int main()
{
printf("hello, world\n");
return 0;
}
I typed this down in a text file named main.c and compiled with gcc main.c -O program (or program.exe on Windows) and then ran program - it works and I'm told not to worry about all the details yet.
Still I am looking for a more more in-depth explanation of this code. What does all of this mean, in great detail?
(This is a self-answered Q&A aimed to those who aren't satisfied with the explanation "just accept that this works for now". Accepting this for now would normally be a very sensible approach if you just picked up C or even programming overall, but there are always those who insist on learning all the details still.)
