Std::distance In Cpp Code Example

Example: std distance c++

// C++ program to demonstrate std::distance()  #include <iostream>  #include <vector>  #include <iterator>  using namespace std;  int main()  {      vector<int> v;      int i;         for (i = 0; i < 10; ++i)       {          v.push_back(i);      }         /*v contains 0 1 2 3 4 5 6 7 8 9*/        vector<int>::iterator first;      vector<int>::iterator last;         // first pointing to 0      first = v.begin();         // last pointing to 5      last = v.begin() + 5;         // Calculating no. of elements between first and last      int num = std::distance(first, last);         // Displaying num      cout << num << "\n";      return 0;  }
