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.
Portions of the Idaho, Montana, South Dakota, Texas, Utah, and Wyoming road networks have 80 mph (129 km/h) limits. The highest posted speed limit in the entire country can be found in one single stretch of rural freeway in Texas, and it is 85 mph (137 km/h). For 13 years (January 1974âApril 1987), federal law prohibited speed limits above 55 mph (89 km/h).
