An array or vector of int or double or any other signed type can achieve this. If the array must alternate, then simply traverse the array alternating the signs as you go: std::vector<int> v = { 1, 2, 3, 4, 5, 6, 7, 8, 9 }; bool sign=true; // true is positive. for (int i=0; i<9; ++i) { if (sign) { // value must be positive if (v[i]<0) v[i] *= -1; // if negative, make positive } else { // value must be negative if (0<v[i]) v[i] *= -1; // if positive, make negative } sign = !sign; // switch sign for next iteration }
