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
