如何找到数组中的元素数量？

const myArray = [1, 2, 3, 4, 5];
console.log(myArray.length); // 输出: 5

myArray = [1, 2, 3, 4, 5]
print(len(myArray))  # 输出: 5

int[] myArray = {1, 2, 3, 4, 5};
System.out.println(myArray.length); // 输出: 5

#include <iostream>
#include <vector>

int main() {
  std::vector<int> myArray = {1, 2, 3, 4, 5};
  std::cout << myArray.size() << std::endl; // 输出: 5
  return 0;
}
