//!
//! Exercise 10.1:
//! The algorithm header defines a function named count that, like find,
//! takes a pair of iterators and a value.count returns a count of how
//! often that value appears.
//! Read a sequence of ints into a vector and print the count of how many
//! elements have a given value.
//!
//! Exercise 10.2:
//! Repeat the previous program, but read values into a list of strings.
//!
#include <iostream>
#include <string>
#include <vector>
#include <algorithm>
#include <list>
int main()
{
//! 10.1
std::vector<int> v = {1, 2, 3, 4, 5, 6, 6, 6, 2};
std::cout << "ex 10.01: " << std::count(v.cbegin(), v.cend(), 6)
<< std::endl;
//! 10.2
std::list<std::string> l = {"aa", "aaa", "aa", "cc"};
std::cout << "ex 10.02: " << std::count(l.cbegin(), l.cend(), "aa")
<< std::endl;
return 0;
}
//! output:
//!
// ex 10.01: 3
// ex 10.02: 2
