If statements
In C, we have conditional statements (aka if statements).
An expression is "tested", and if the result is true, we execute the block
immediately following the if statement "header".
If it's false, we go down the conditional chain.
Note 0: '1' is often used to indicate true, and '0' for false.
Note 1: The 'bool' type was added in C99
