Generic find algorithm: use find function to find an element in an array

  
 
#include <iostream>
#include <cassert>
#include <algorithm>
#include <list>
#include <iterator>
using namespace std;

int main()
{
  int a[10] = {12, 3, 25, 7, 11, 213, 7, 123, 29, -31};

  // Find the first element equal to 7 in the array:
  int* ptr = find(&a[0], &a[10], 7);

  assert (*ptr == 7 && *(ptr+1) == 11);

  cout << *ptr;

  return 0;
}

/* 
7
 */
