distance between iterators c++ 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;
