AtCoder：A - Reward of Multiples
【题目描述】
Takahashi is in charge of accounting at his company and is managing this month's bonus payments to employees.
高桥负责公司的会计工作，正在管理本月给员工的奖金发放。
The company has \(N\) employees, and each employee has a compensation amount determined by their performance. The compensation amount for the \(i\)-th employee is \(P_i\) yen.
公司有 \(N\) 名员工，每位员工的奖金金额根据其绩效确定。第 \(i\) 名员工的奖金金额为 \(P_i\) 日元。
The company president gave the following instruction: "I would like to give a special allowance to employees whose compensation amount is a multiple of \(K\). First, please tell me the total of the compensation amounts for the applicable employees."
公司总裁给出了以下指示："我希望向奖金金额是 \(K\) 的倍数的员工发放特殊津贴。首先，请告诉我符合条件员工的奖金金额总和。"
Help Takahashi find the total of the compensation amounts for employees whose compensation amount is a multiple of \(K\) (that is, \(P_i\) is divisible by \(K\)). If there are no such employees, the total is \(0\).
帮助高桥计算奖金金额是 \(K\) 的倍数（即 \(P_i\) 能被 \(K\) 整除）的员工奖金金额总和。如果不存在这样的员工，总和为 \(0\)。
【输入】
\(N\) \(K\)
\(P_1\) \(P_2\) \(\ldots\) \(P_N\)
- The first line contains an integer \(N\) representing the number of employees and an integer \(K\) used for the divisibility check, separated by a space.
- The second line contains \(N\) integers \(P_1, P_2, \ldots, P_N\) representing the compensation amounts of each employee, separated by spaces.
【输出】
Print the total of the compensation amounts for employees whose compensation amount is a multiple of \(K\), on a single line.

【代码详解】
#include <bits/stdc++.h>
using namespace std;
#define int long long
int n, k, ans; // n: 数据个数，k: 除数，ans: 总和signed main()
{cin >> n >> k; // 读入数据个数和除数for (int i = 1; i <= n; i++){int x; cin >> x; // 读入当前数字if (x % k == 0) // 如果当前数字能被k整除{ans += x; // 累加到总和中}}cout << ans << endl; // 输出总和return 0;
}
【运行结果】
