25.4.2.Use count on string
#include <iostream>
#include <string>
#include <algorithm>
using namespace std;

int main()
{
  string str1("Strings handling is easy in C++");
  string::iterator p;
  unsigned int i;

  // use the count() algorithm
  i = count(str1.begin(), str1.end()'i');
  cout << "There are " << i << " i's in str1\n";

  return 0;
}
There are 4 i's in str1
