C++类属性unique

类属性算法unique的作用是从输入序列中去掉所有相邻的重复元素。

1 #include <iostream> 2 #include <cassert> 3 #include <algorithm> 4 #include <vector> 5 #include <string> 6 #include <iterator> 7  using namespace std; 8  9  int main()10 {11     cout<<"Illustrating the generic unique algorithm."<<endl;12     const int N=11;13     int array1[N]={1,2,0,3,3,0,7,7,7,0,8};14     vector<int> vector1;15     for (int i=0;i<N;++i)16         vector1.push_back(array1[i]);17 18     vector<int>::iterator new_end;19     new_end=unique(vector1.begin(),vector1.end());20     assert(vector1.size()==N);21 22     vector1.erase(new_end,vector1.end());23     copy(vector1.begin(),vector1.end(),ostream_iterator<int>(cout," "));24     cout<<endl;25 26     return 0;27 }

输出结果为

Illustrating the generic unique algorithm.
