Pair programming Pair Programming, 2009. Pair programming is a software development technique in which two programmers work together at one workstation. One, the driver, writes code while the other, the observer or navigator, [1] reviews each line of code as it is typed in. The two programmers switch roles frequently.
The pairs are not fixed; programmers switch partners frequently, so that everyone knows what everyone is doing, and everybody remains familiar with the whole system, even the parts outside their skill set. This way, pair programming also can enhance team-wide communication. (This also goes hand-in-hand with the concept of Collective Ownership).
Suppose that one wants to define what it means for two sets to "have the same number of elements". One way to do this is to say that two sets "have the same number of elements", if and only if all the elements of one set can be paired with the elements of the other, in such a way that each element is paired with exactly one element.
The hospitals/residents problem with couples allows the set of residents to include couples who must be assigned together, either to the same hospital or to a specific pair of hospitals chosen by the couple (e.g., a married couple want to ensure that they will stay together and not be stuck in programs that are far away from each other).
Definition Usage Variable: A storage location paired with an associated symbolic name that contains some known or unknown quantity of information referred to as a value. Typically used in all programming paradigms. Function: An abstraction representing a set of instructions that can be applied to input data to produce output.
Currying is related to, but not the same as, partial application. [1] [2] The example above can be used to illustrate partial application; it is quite similar. Partial application is the function that takes the pair and together as arguments, and returns .
A matching is a set of n disjoint pairs of participants. A matching M in an instance of SRP is stable if there are no two participants x and y, each of whom prefers the other to their partner in M. Such a pair is said to block M, or to be a blocking pair with respect to M.
This can be more related to pair programming and exploratory testing of agile software development where two team members are sitting together to test the software application. This will help both the members to learn more about the application. This will narrow down the root cause of the problem while continuous testing.
