fix spelling
- I am trying to print "hello, world" on screen in in C using this code:
- ```c
- #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?

Detailed explanation of "hello, world" in C?
I am trying to print "hello, world" on screen in in C using this code:
```c
#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?
