以下程序执行后的输出结果是 class Program { static void Main(string[] args) { int[] a = {12,9,76,-90,23,100,87,32}; for (int i = 2; i < 4; i++) { int t; for (int j = i + 1; j <5; j++) { if (a[i] < a[j]) { t = a[i]; a[i] = a[j];a[j] = t; } } } for (int i = 0; i < 8; i++) Console.Write("{0} ", a[i]); Console.WriteLine(); } }
