  1. Combine two different types of data together. The pair can be used to combine two different types of data into one object, making it easy to return multiple values in a function or store multiple types of data in a container.<\/li>\n
  2. Store key-value pairs in a container. Pairs can be used to store key-value pairs, such as storing associated key-value pairs in map or unordered_map containers.<\/li>\n
  3. As a return value of a function, a pair can be used to easily return multiple values.<\/li>\n
  4. In algorithms, some functions like sort and min\/max can utilize pairs to specify the range for sorting or searching.<\/li>\n
  5. Pair can be used in custom data structures to store two related pieces of data.<\/li>\n<\/ol>\n

    In general, the usage of pairs in C++ is very versatile, as it can be used in various situations where two pieces of data need to be combined.<\/p>\n","protected":false},"excerpt":{"rendered":"
