API - application program interface. Related Terms. Application program interface (API) is a set of routines, protocols, and tools for building software applications. An API specifies how software components should interact. Additionally, APIs are used when programming graphical user interface (GUI) components. A good API makes it easier to develop a program by providing all the building blocks.
By Rowena Pedrena. A traditional golf set has 13 clubs: three woods, nine irons (including three wedges) and one putter. The USGA limits the number of clubs a player may carry in his or her bag to 14. A player may include an additional wedge or wood to a fill a gap in hitting distance.
No golfer may have more than 14 clubs. There is no minimum, but golfers who carry more than 14 are in violation of the rules. For most high-and medium-handicap golfers, that's more than enough. However, for top pros and low-handicap golfers, it may be tough to choose which clubs to carry.
