in c++

Write a program that keeps reading in integer values. If an input value is positive, store it in a vector. If the input value is negative, you will remove all existing values in your vector with the same absolute value. When O is read output the number of entries that remained in the vector and the sum of all entries. Then stop. Input: For example, the user inputs in sequence, 1 2 3 4 5 6-50 Output: 1 2 3 46 16
