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(); } } }
