Functions (C++) A function is a block of code that performs some operation. A function can optionally define input parameters that enable callers to pass arguments into the function. A function can optionally return a value as output. Functions are useful for encapsulating common operations in a single reusable block, ideally with a name that clearly describes what the function does. The following function accepts two integers from a caller and returns their sum; a and b are parameters of type int.

On secondary roads (those routes numbered 600 and above, with one exception), the limits are 45 mph for trucks and 55 mph for other vehicles. Effective July 1, 2014, a maximum speed limit of 35 mph applies to all unpaved roads statewide.The road does not have to be posted.
