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 relevance of the 40 mile per hour (mph) posted minimum speed limit found on the Interstate Highway System is increasingly being called into question in light of the National Highway System Designation Act of 1995, which repealed the federally sanctioned maximum speed limit of 65 mph on rural highways.
