在C#中交换两个数字
要交换两个数字，请使用以下逻辑。
设置两个变量进行交换-
val1 = 100; val2 = 200;
现在对交换执行以下操作-
val1 = val1 + val2; val2 = val1 - val2; val1 = val1 - val2;
以下是代码-
示例
using System;
namespace Demo {
class Program {
static void Main(string[] args) {
int val1,val2;
val1 = 100;
val2 = 200;
Console.WriteLine("Values before swap...");
Console.WriteLine(val1.ToString());
Console.WriteLine(val2.ToString());
val1 = val1 + val2;
val2 = val1 - val2;
val1 = val1 - val2;
Console.WriteLine("Values after swap...");
Console.WriteLine(val1.ToString());
Console.WriteLine(val2.ToString());
Console.ReadLine();
}
}
}
