c++ std::find algorithm example

C++ standard library has many useful features. One of which is the std::find algorithm.


Here is a simple example:

#include <iostream>
#include <algorithm>

int main() {
  int data[100];
  data[89] = 7;
  int * where = std::find(data,data+100,7);
  std::cout << *where << std::endl;
}

This will output '7'. The interesting part is the algorithm will work with any data structure not just arrays.

#include <iostream>
#include <algorithm>
#include <list>
int main() {
  std::list<int> data;
  data.push_back(3);
  data.push_back(7);
  data.push_back(9);
  std::list<int>::iterator where = std::find(data.begin(),data.end(),7);
  std::cout << *where << std::endl;
}
