WebGeneric programming is a style of computer programming in which algorithms are written in terms of types to-be-specified-later that are then instantiated when needed for specific types provided as parameters.This approach, pioneered by the ML programming language in 1973, permits writing common functions or types that differ only in the set of types on For example, if -2, 147, 483, 648 is stored in an int data type and 1 is subtracted from it, the value in that variable will become equal to 2, 147, 483, 647.
