基础练习

#include <iostream>
#include <algorithm>

using namespace std;

int main()
{
    int number[10];

    for (int i = 0; i < 10; i++)
        number[i] = i * 2;

    //返回值为bool类型
    if (binary_search(number, number+10, 2))
        cout << "Found!\n";
    else
        cout << "Not Found!\n";

    int *numPtr = find(number, number+10, 2);//返回值类型为迭代器或者指针

    if (numPtr != NULL)
        cout << "Found!\n";
    else
        cout << "Not Found!\n";
    cin.get();
    return 0;
}
