宣布一个数组的长度

array = [1, 2, 3, 4, 5]
length = len(array)
print("数组长度为：", length)

const array = [1, 2, 3, 4, 5];
const length = array.length;
console.log("数组长度为：", length);

int[] array = {1, 2, 3, 4, 5};
int length = array.length;
System.out.println("数组长度为：" + length);

int[] array = {1, 2, 3, 4, 5};
int length = array.Length;
Console.WriteLine("数组长度为：" + length);

#include<iostream>
#include<vector>

int main() {
    std::vector<int> array = {1, 2, 3, 4, 5};
    int length = array.size();
    std::cout << "数组长度为："<< length<< std::endl;
    return 0;
