晚上看了下入门经典的书.有几道题.嘿嘿..所以就做了下
using System;
using System.Collections.Generic;
using System.Text;
namespace chap1
...{
class Program
...{
static void Main(string[] args)
...{
Console.WriteLine("输入字符");
string str=Console.ReadLine();
string des = "";
//给字符串的每个单词加上双引号
string[] words = System.Text.RegularExpressions.Regex.Split(str, @"W+");
foreach (string word in words)
...{
//得出结果
string temps = """ + word + """;
Console.WriteLine(temps);
}
//为一句话或一段加上引号
//string st = """ + str + """;
//Console.WriteLine(st);
char [] temp=str.ToCharArray();
//输入相反的输出
for (int i = temp.Length - 1; i >= 0;i--)
...{
des += temp[i];
}
//替换字符
des = str.Replace("no","yes");
Console.WriteLine(des);
}
}
}
using System;using System.Collections.Generic;using System.Text;namespace chap1...{ class Program ...{ static void Main(string[] args) ...{ Console.WriteLine("输入字符"); string str=Console.ReadLine(); string des = ""; //给字符串的每个单词加上双引号 string[] words = System.Text.RegularExpressions.Regex.Split(str, @"W+"); foreach (string word in words) ...{ //得出结果 string temps = """ + word + """; Console.WriteLine(temps); } //为一句话或一段加上引号 //string st = """ + str + """; //Console.WriteLine(st); char [] temp=str.ToCharArray(); //输入相反的输出 for (int i = temp.Length - 1; i >= 0;i--) ...{ des += temp[i]; } //替换字符 des = str.Replace("no","yes"); Console.WriteLine(des); } }}
