In c++

write a program called pairwise. cpp that implements the function vector sumpairwise(const vector & v1, const vector & v2) that returns a vector of integers whose elements are the pairwise sum of the elements from the two vectors passed as arguments. if a vector has a smaller size than the other, consider extra entries from the shorter vectors as 0. example:

vector v1{1,2,3};
vector v2{4,5};

sumpairwise(v1, v2); // returns [5, 7, 3]
