C语言每日练习之统计文本单词数及高频词

作业1:统计出txt文本里面的单词数，并找出频率出现最高的单词是哪个？

运行结果：

上代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            //文件打开
            //string file = System.IO.File.ReadAllLines(@"");
            int count = 0;
            string tmp = "";
            //初始化次数
            string words = "hihi hello,hihi,hello,hihi?";
            var new_i = words.Split(new char[] { ' ', ',', '.', '?' },StringSplitOptions.RemoveEmptyEntries);
            Console.Write("总的单词数量：{0}\n", new_i.Length);
            for (int i = 0; i < new_i.Length; i++)
            {
                //查询每个单词出现的次数
                var query = from key in new_i where key.ToUpperInvariant() == new_i[i].ToUpperInvariant() select key;
                int key_count = query.Count();
                if (key_count > count) {

                    count = key_count;
                    tmp = new_i[i];
                }

            }

            Console.Write("频率出现最高的单词是：{0}\n", tmp);
            Console.Write("次数为：{0}\n", count);

            Console.ReadKey();

        }
    }
}

基础代码运行成功！通过外部打开！

创建11.txt

通过外部打开：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            //文件打开
            //string[] file_A = System.IO.File.ReadAllLines(@"C:\Users\Administrator\Desktop\11.txt");
            string file_A = System.IO.File.ReadAllText(@"C:\Users\Administrator\Desktop\11.txt");
            //Console.Write(file_A);
            int count = 0;
            string tmp = "";
            //初始化次数

            var new_i = file_A.Split(new char[] { ' ', ',', '.', '?' }, StringSplitOptions.RemoveEmptyEntries);
            Console.Write("总的单词数量：{0}\n", new_i.Length);
            for (int i = 0; i < new_i.Length; i++)
            {
                //查询每个单词出现的次数
                var query = from key in new_i where key.ToUpperInvariant() == new_i[i].ToUpperInvariant() select key;
                int key_count = query.Count();
                if (key_count > count) {

                    count = key_count;
                    tmp = new_i[i];
                }

            }

            Console.Write("频率出现最高的单词是：{0}\n", tmp);
            Console.Write("次数为：{0}\n", count);

            Console.ReadKey();

        }
    }
}
