将数组变量名转换为字符串

var arr = [1, 2, 3];
var arrName = arr.toString();
console.log(arrName); // 输出 "1,2,3"

arr = [1, 2, 3]
arrName = str(arr)
print(arrName) # 输出 "[1, 2, 3]"

int[] arr = {1, 2, 3};
String arrName = Arrays.toString(arr);
System.out.println(arrName); // 输出 "[1, 2, 3]"

#include <iostream>
#include <string>
using namespace std;

int main() {
    int arr[] = {1, 2, 3};
    string arrName = to_string(arr);
    cout << arrName << endl; // 输出 "1"
    return 0;
}
