Always write if statements with braces

By putting braces around every block of code you write, you ensure that future edits won't introduce bizarre bugs.

If you have a one-line if statement:
if(<condition>)
execute();
you should still surround

execute();

with braces:
if(<condition>)
{
execute();
}
Now, if you go back and add a second instruction
if(<condition>)
{
execute();
execute2();
}
you don't have to worry about putting in the braces, and you know that you won't forget to put them in.
