Compiling C programs on Ubuntu 12.04

Question

I'm an absolute beginner at writing programs in C, and I'm having difficulty compiling a simple program. Here's my code:

/* This code is a .c file that prints out the words hello, world. */

# include <stdio.h>
int main()
{
    printf("Hello World! \n");
}

Here's the error I get when compiling:

Ubuntu:~/Desktop/cFiles$ gcc -Wall hello.c -o hello.out -lmls 
hello.c:5:1: warning: return type defaults to ‘int’ [-Wreturn-type]
hello.c: In function ‘main’:
hello.c:7:3: warning: implicit declaration of function ‘print’ [-Wimplicit-function-declaration]
hello.c:8:1: warning: control reaches end of non-void function [-Wreturn-type] /usr/bin/ld: cannot find -lmls
collect2: ld returned 1 exit status

I'm not sure what I'm doing wrong. Can anyone help?

Answer 1

Seems like you have an unwanted space between # and include:

# include <stdio.h>   

Make that

#include <stdio.h> 

and compile.
That should solve it for you.
