c++ language

given function signature int minValue(const int &v1, const int &v2, const int &v3); write the function - it should return the minimum of v1, v2, and v3. Given the function signature void inOrder(int &v1, int &v2, int &v3); write the function - it should put the 3 values in order. You will need swap: void swap(int &a, int &b) { int tmp = a; a = b; b = tmp; }
