Question

用C#编程:输入一些给定的字符串,统计它们各自出现的次数

Answer 1

using System;using System.Collections.Generic;using System.Linq;using System.Text;
namespace ConsoleApplication1{ class Program { static void Main(string[] args) { List<String> record = new List<String>() { "Hello","World","This","is","my","first","try","to","say","Hello" };
var query = from r in record group r by r.ToLower() into g select new { Count = g.Count(), Value = g.Key };
foreach (var v in query) { Console.WriteLine("Value = {0}, Count = {1}", v.Value, v.Count); } } }}使用LINQ TO OBJECT，一句话就搞定了

Answer 2

附上程序#include <iostream>#include <cstdlib>using namespace std;int main(void)unsigned NumDigit(unsigned n);//我相信这个整数不会超过255位吧 unsigned res = 0; itoa(n, c, 10); for (int i = 0; c[i] != NULL; ++i) res++; return res;}
