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.
Maximum Speed Limit The law sets the maximum at 70 mph, but allows the Texas Transportation Commission to establish a maximum speed limit of 75 mph (80 mph or 85 mph if the highway is designed to accommodate that speed) on the highway system if that speed is determined to be safe and reasonable after a traffic or engineering study.
