halpers.c:1:20: error: stdio.h: No such file or directory
halpers.c: In function 'main':
halpers.c:5: warning: incompatible implicit declaration of built-in function 'printf'
halpers.c:4: warning: return type of 'main' is not 'int'
Text editing files is only getting me so far. So...
is there a practical and updated set of tutorials for c and c++ that can be/ are used for freebsd?
It isn't running or editing c files that causes a problem. it's trying to write them.

man 3 printf

[sossego]

#include < stdio.h>

void main()
{
printf("\n Hello World \n");
}


I know, it's the standard c tutorial; but, I'm not seeing something here.

Look at the include line... You have an extra space in there.

It's the same output after editing. I am looking at a few references that say I may be missing some header/developer files. Question is which ones?

[SirDice]

No, your #include line should read:

#include <stdio.h>


There's a space in yours..

stdio.h lives in /usr/include:

dice@williscorto:~>ll /usr/include/stdio.h
-r--r--r-- 1 root wheel 14752 Apr 25 2008 /usr/include/stdio.h

[SirDice]

Works like a charm:

dice@williscorto:~/test>cat test.c
#include <stdio.h>

int main () {
printf("\nHello World\n");
return 0;
}

dice@williscorto:~/test>cc -o test test.c
dice@williscorto:~/test>./test

Hello World
dice@williscorto:~/test>

Minha culpa (My fault). Thanks for showing me that.

Try to get C Primer Plus by Stephen Prata. It's more comprehensive than K&R and the author assumes that you have no programming experience. There are tons of examples, too.

Also, maybe use an IDE with syntax highlighting.

i used to use codelite for a c ide. pretty good.
