求和平均值.txt

c语言多个实用小程序,会有帮助的~ 自己瞎编的

using System;
using System.Collections;
class Sum_Average
{
	public static void Main()
	{
		int sum=0;
		float average=0.0f;
		Random r=new Random ();
		ArrayList myArrayList=new ArrayList ();
		Console.WriteLine ("你想算几个数的和,并求它的平均值:");
		int iMax=int.Parse (Console.ReadLine ());
		for(int i=0;i<iMax;i++)
		{
			myArrayList.Add (r.Next (0,100));
		}
		Console.WriteLine ("这{0}个数是:",iMax);
		foreach(int pins in myArrayList)
		{
			Console.WriteLine (pins);
		}
		for(int j=0;j<iMax;j++)
		{
			sum+=(int)myArrayList[j];
		}
		Console.WriteLine ("这{0}个数的和是:{1}",iMax,sum);
		average = (float)sum / iMax;
		Console.WriteLine ("这{0}个数的平均值是:{1}",iMax,average);
