## c 連接字符

Input characters and compare them using C# program.

輸入字符并使用C＃程序進行比較。

Prerequisite: Methods to input a single character in C#

先決條件： 在C＃中輸入單個字符的方法

C＃代碼比較兩個字符 (C# code to compare two characters)

Here, we are asking for two characters from the user – and checking whether they are the same characters or not?

在這里，我們要求用戶輸入兩個字符-并檢查它們是否相同？

// C# program for character comparison using System; using System.IO; using System.Text;namespace IncludeHelp {class Test{// Main Method static void Main(string[] args){char ch1;char ch2;//input charactersConsole.Write("Enter a character: ");ch1 = Console.ReadLine()[0];Console.Write("Enter another character: ");ch2 = Console.ReadLine()[0];//comparing charactersif (ch1 == ch2)Console.WriteLine("Input characters are the same");elseConsole.WriteLine("Input characters are not the same");//hit ENTER to exit the programConsole.ReadLine();}} }

Output

輸出量

First run: Enter a character: A Enter another character: A Input characters are the sameSecond run: Enter a character: A Enter another character: X Input characters are not the same

C＃代碼比較字符串中的字符 (C# code to compare characters in a string)

Here, we are asking for a string from the user – and printing only vowels by comparing each character of the string with vowel characters.

在這里，我們要求用戶輸入字符串，并且通過將字符串的每個字符與元音字符進行比較來僅打印元音。

// C# program for character comparison using System; using System.IO; using System.Text;namespace IncludeHelp {class Test{// Main Method static void Main(string[] args){string str;//input stringConsole.Write("Enter a string: ");str = Console.ReadLine();//printing the stringConsole.WriteLine("Input string is {0}", str);//printing vowels Console.WriteLine("Vowels are...");foreach (char ch in str){if (ch == 'A' || ch == 'a' || ch == 'E' || ch == 'e' ||ch == 'I' || ch == 'i' || ch == 'O' || ch == 'o' || ch == 'U' || ch == 'u'){Console.Write(ch);}}//hit ENTER to exit the programConsole.ReadLine();}} }

Output

輸出量

Enter a string: IncludeHelp.com Input string is IncludeHelp.com Vowels are... Iueeo
