welcome to the blockland community. don't make any mistakes because if you do then people will bandwagon and bash you for it even if time advances by five years. I learned this the hard way.
#include <stdio.h>
int main()
{
printf("Hello LegoFish, welcome to Blockland Forums")
return 42;
}
1: There's no semicolon on line 5
2: You should not return 42 for main(), a common practice is to return 0
3: Iostream (std::cout << x) is better than printf
EDIT: Sorry. I just had to...
