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.
Speed limits will rise from 55 to 60 mph as soon as the Minnesota Department of Transportation (MnDOT) can get new signs up along 340 miles of state and federal highways, including long segments of Hwys.
The legislative mandate required MnDOT to study all two-lane highways that have a speed limit of 55 mph over a five-year period. In 2014, the department evaluated 570 miles of highway and deemed 340 miles of them appropriate for higher speed, according to a report submitted to the Legislature in January.
