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.
Washington allows for speeds up to 75 miles per hour (121 km/h), but the highest posted signs are 70 miles per hour (110 km/h). Mississippi allows speeds up to 80 mph (130 km/h) on toll roads, but no such roads exist. Oklahoma removed the maximum speed of 75 from its laws, though no road been posted higher than 75.
