找到平均值。 int数组的最大，最小数量和模式

嗨我正在尝试创建一个程序，用户可以输入最多25个数字然后它告诉用户平均，最小和最大数字和输入数字的模式，但我不知道如何做到这一点。

任何指导将不胜感激

这是我到目前为止所拥有的

static void Main(string[] args) { Console.WriteLine("enter the amount of numbers you would like to use of: "); int arraylength = Int32.Parse(Console.ReadLine()); int[] AverageArray = new int[25]; //filling the array with user input for (int i = 0; i < AverageArray.Length; i++) { Console.Write("enter the numbers you wish to find the average for: "); AverageArray[i] = Int32.Parse(Console.ReadLine()); } //printing out the array Console.WriteLine("here is the average: "); for (int i = 0; i < AverageArray.Length; i++) { Console.WriteLine(AverageArray[i]); } Console.WriteLine(FindAverage(AverageArray)); } public static double FindAverage(int[] averageNumbers) { int arraySum = 0; for (int i = 0; i < averageNumbers.Length; i++) arraySum += averageNumbers[i]; return arraySum / averageNumbers.Length; } public static double LargestNumber(int[] Nums, int Count) { } public static double SmallestNumber(int[] Nums, int Count) { } public static double Mode(int[] Nums, int Count) { } } 

Answer 1

 public static double LargestNumber(int[] Nums, int Count) { double max = Nums[0]; for (int i = 1; i < Count; i++) if (Nums[i] > max) max = Nums[i]; return min; } public static double SmallestNumber(int[] Nums, int Count) { double min = Nums[0]; for (int i = 1; i < Count; i++) if (Nums[i] < min) min = Nums[i]; return min; } public static double Mode(int[] Nums, int Count) { double mode = Nums[0]; int maxCount = 1; for (int i = 0; i < Count; i++) { int val = Nums[i]; int count = 1; for (int j = i+1; j < Count; j++) { if (Nums[j] == val) count++; } if (count > maxCount) { mode = val; maxCount = count; } } return mode; } 

Answer 2

 var smallest = AverageArray.Min(); var largest = AverageArray.Max(); var mode = AverageArray.GroupBy(v => v) .OrderByDescending(g => g.Count()) .First() .Key; 

Answer 3

如果您不知道如何使用linq

  /*Assign Initial Value*/ int highestNum = numberArray[0]; int lowestNum = numberArray[0]; int sum = 0; foreach (int item in numberArray) { /*Get The Highest Number*/ if (item > highestNum) { highestNum = item; } /*Get The Lowest Number*/ if (item < highestNum) { lowestNum = item; } //get the sum sum = item + sum; } //display the Highest Num Console.WriteLine(highestNum); //display the Lowest Num Console.WriteLine(lowestNum); //Display The Average up to 2 decimal Places Console.WriteLine((sum/numberArray.Length).ToString("0.00"));
