查找C++中5个不同元素的最小和最大元素

int arr[5] = {2, 7, 1, 4, 9};

int minNum = arr[0];
int maxNum = arr[0];

for (int i = 1; i < 5; i++) {
    if (arr[i] < minNum) {
        minNum = arr[i];
    }
    if (arr[i] > maxNum) {
        maxNum = arr[i];
    }
}

#include <iostream>

int main() {
    int arr[5] = {2, 7, 1, 4, 9};
    int minNum = arr[0];
    int maxNum = arr[0];
    
    for (int i = 1; i < 5; i++) {
        if (arr[i] < minNum) {
            minNum = arr[i];
        }
        if (arr[i] > maxNum) {
            maxNum = arr[i];
        }
    }
    
    std::cout << "最小值: " << minNum << std::endl;
    std::cout << "最大值: " << maxNum << std::endl;
    
    return 0;
}

最小值: 1
最大值: 9
