Looking at the following C++ snippet that manages a pair ofintegers.

Part A: Write code that creates a C++ vector of the PairOfIntsand add two pairs to the vector with the numbers (1,2) and(10,20).
Part B: Re-write the class above as PairOfAnything so we canmake a pair of any type using templates. For example, the followingwould make a pair of strings. PairOfAnythingstringPair("foo","bar");

class PairOfInts { private: int p1; int p2; public: }; PairOfInts(int p1, int p2); void print(); PairOfInts::PairOfInts(int p1, int p2) : p1(p1), p2(p2) { } void PairOfInts::print() { cout < < p1 < < " " < < p2 < < endl; }
