getting error while compiling c programs

I am new to Linux os and i installed ubuntu juanty two days before.
i have installed build essential packages and other packages required to compile c code. But while compiling simple c program (which only prints the message ) i am getting error.
the code is:-

#include<stdio.h>
int main
{
 printf("this is sit\n");
return 0;
}

i'm getting the below error:-

sample.c:3: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘{’ token

so tell me what to do ???
