        static void Main(string[] arg){int intSum = 0;for (int i = 0; i <= 100; i++){intSum += i;}Console.WriteLine(intSum);Console.ReadKey();}

        static void Main(string[] arg){for (int i = 0; i < 100; i++){Console.WriteLine("我下次一定小心!");//打印"我下次一定小心"
            }Console.ReadKey();}

        static void Main(string[] arg){int sum = 0;for (int i = 0; i < 100; i++){if (i%2==0){sum += i;}}Console.WriteLine(sum);Console.ReadKey();}
