C++数组、vector求最大值最小值及其下标

#include <iostream>
#include <vector>
#include <algorithm> // 包含 std::max_element 和 std::min_element


int main() {
    std::vector<int> vec = {3, 1, 4, 2, 5};

    // 查找最大值及其索引
    auto maxIt = std::max_element(vec.begin(), vec.end());
    int maxValue = *maxIt;
    int maxIndex = std::distance(vec.begin(), maxIt);

    // 查找最小值及其索引
    auto minIt = std::min_element(vec.begin(), vec.end());
    int minValue = *minIt;
    int minIndex = std::distance(vec.begin(), minIt);

    // 输出向量内容
    std::cout << "向量: ";
    for (int num : vec) {
        std::cout << num << " ";
    }
    std::cout << "\n";

    // 输出最大值及其索引
    std::cout << "最大值: " << maxValue << "，索引: " << maxIndex << "\n";
    // 输出最小值及其索引
    std::cout << "最小值: " << minValue << "，索引: " << minIndex << "\n";

    return 0;
