#include ＜algorithm＞应用

在看这篇文章之前，先看看#include <algorithm>的简介。

#include ＜algorithm＞https://blog.youkuaiyun.com/NOIP1ding_c/article/details/144294173这篇文章我来给大家几个algorithm的应用。  

应用

应用一

#include <algorithm>
#include <vector>
#include <iostream>
int main() {
    std::vector<int> numbers = {5, 2, 9, 1, 5, 6};
    std::sort(numbers.begin(), numbers.end());
    for (int num : numbers) {
        std::cout << num << " ";
    }
    std::cout << std::endl;
    return 0;
}

应用二

#include <algorithm>
#include <vector>
#include <iostream>
int main() {
    std::vector<int> numbers = {1, 2, 3, 4, 5};
    auto it = std::find(numbers.begin(), numbers.end(), 3);
    if (it != numbers.end()) {
        std::cout << "Found: " << *it << std::endl;
    } else {
        std::cout << "Value not found." << std::endl;
    }
    return 0;
}

应用三

#include <algorithm>
#include <vector>
#include <iostream>
int main() {
    std::vector<int> source = {1, 2, 3, 4, 5};
    int destination[5];
    std::copy(source.begin(), source.end(), destination);
    for (int i = 0; i < 5; ++i) {
        std::cout << destination[i] << " ";
    }
    std::cout << std::endl;
    return 0;
}

应用四

#include <algorithm>
#include <vector>
#include <iostream>
int main() {
    std::vector<int> v1 = {1, 2, 3, 4, 5};
    std::vector<int> v2 = {1, 2, 3, 4, 5};
    bool are_equal = std::equal(v1.begin(), v1.end(), v2.begin());
    std::cout << (are_equal ? "Vectors are equal." : "Vectors are not equal.") << std::endl;
    return 0;
}
