循环要求和和求平均值的列的列表

# 列表示例
data = [1, 2, 3, 4, 5]

# 求和
total = 0
for num in data:
    total += num
print("总和：", total)

# 求平均值
average = total / len(data)
print("平均值：", average)

// 列表示例
int[] data = {1, 2, 3, 4, 5};

// 求和
int total = 0;
for (int num : data) {
    total += num;
}
System.out.println("总和：" + total);

// 求平均值
double average = (double) total / data.length;
System.out.println("平均值：" + average);

#include <iostream>
using namespace std;

// 列表示例
int data[] = {1, 2, 3, 4, 5};
int size = sizeof(data) / sizeof(data[0]);

// 求和
int total = 0;
for (int i = 0; i < size; i++) {
    total += data[i];
}
cout << "总和：" << total << endl;

// 求平均值
double average = (double) total / size;
cout << "平均值：" << average << endl;
