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 posted speed limit is 30 mph. A sample size of 93 vehicles was measured, and the resulting critical speed is 27 mph; therefore, the recommended speed limit is 25 mph. The accident rate for this segment is 2.15, and the 10 mph pace is 21 to 30 mph.
