C# 程序确定数组中任意两个整数之和是否等于给定整数
csharpprogrammingserver side programming更新于 2025/9/19
以下是我们的数组 −
int[] arr = new int[] {
7,
4,
6,
2
};
假设给定的整数应该等于另外两个整数之和，即 −
int res = 8;
获取和并找到相等性。
for (int i = 0; i < arr.Length; i++) {
for (int j = 0; j < arr.Length; j++) {
if (i != j) {
int sum = arr[i] + arr[j];
if (sum == res) {
Console.WriteLine(arr[i]);
}
}
}
}
示例
using System;
using System.Collections.Generic;
namespace Demo {
public class Program {
public static void Main(string[] args) {
int[] arr = new int[] {
7,
4,
6,
2
};
// given integer
int res = 8;
Console.WriteLine("Given Integer {0}: ", res);
Console.WriteLine("Sum of:");
for (int i = 0; i < arr.Length; i++) {
for (int j = 0; j < arr.Length; j++) {
if (i != j) {
int sum = arr[i] + arr[j];
if (sum == res) {
Console.WriteLine(arr[i]);
}
}
}
}
}
}
}
