Your mistakes

  1. at line no 4 correct is int n=A.size();
  2. from line no 12 to 14
    you are doing wrong
    you have to return vector of vector not a single vector
    so first make a vector of triplet and then push this vector into v
    so correct way to do this is

vector<int>temp;

                temp.push_back(A[i]);

                temp.push_back(A[j]);

                temp.push_back(A[k]);

                v.push_back(temp);

                j++;

now even after this you output will contains some repeated terms
so to remove repetition put the vector into set and then put again into vector

see the modified code for details
