Open up a console window.

type vi hello.c and use the vi editor to create the file.

Then use gcc to compile the file, and run the resulting a.out file.

Here is the file, and the steps to compile and run:


root@slax:~# cat hello.c
/* Hello World program */

#include

main()
{
printf("Hello World\n");
}
root@slax:~# gcc hello.c
root@slax:~# ls
Desktop/ a.out* hello.c
root@slax:~# ./a.out
Hello World
root@slax:~#

Oops, the web interface messed up the #include line. Should be:
#include\

Dammit. The line should be #include stdio.h, with stdio.h enclosed in angle brackets.

Write the program (from a console):

cat > main.c <<EOF
#include <stdio.h>
int main(void)
{
printf("Hello World!\n");
return 0;
}
EOF

build:

gcc main.c -o hello

run:

./hello

Yes. I was about to say what vonbiber was going to say. :) That'd be what I'd recommend doing. You could use echo as well here, instead of cat:


root@slax# echo "\
#include <stdio.h>
int main()
{
*/ Display the greeting here /*
printf("hello world\n");
*/ Quit /*
return 0;
}" > ccode.c

root@slax# gcc ccode.c -o cprogram
root@slax# ./cprogram


I might add that bash is an undervalued but fully Turing-compliant language that can also make programs (especially when combined with Perl, for instance). In this case, however, this is just a little script, but it can get the simple job done as well:


root@slax# echo "\
#!/bin/bash

# Display the greeting here
echo "Hello, world."
# Quit
exit 0" > bashapp

root@slax# chmod +x bashapp && ./bashapp


Anyway, good luck... :)

Guys, why cap HELLO here? In Python 2/3.x, it can be just like this: print("Hello")
