用空格分隔用戶輸入號碼

Question

我需要將用戶輸入的數字（最多五位數字）與三個空格分開。因此，如果用戶輸入號碼12345，則控制檯打印出「1 2 3 4 5」。

我只是控制檯打印出號碼：

class MainClass 
{ 
    public static void Main (string[] args) 
    { 
     Console.WriteLine ("Please enter in a five digit number: "); 
     string userInput = Console.ReadLine(); 
     Console.WriteLine (userInput); 
     Console.ReadKey(); 
    } 
} 

Answer 1

這應該爲你做的伎倆:)

class MainClass 
{ 
    Console.WriteLine ("Please enter in a five digit number: ") 
    string answer = string.Empty; 
    int userInput = 0; 

    for(int i = 0, i < 5, i++) 
    { 
     userInput = Console.ReadLine(); 

     // Append 3 spaces to each input provided by the user 
     answer = string.Format("{0}{1}{3}",answer, userInput, " "); 
    } 

    Console.WriteLine(answer) 
} 

Answer 2

Hımmm，它看起來像一個功課;）

Console.WriteLine("Please enter in a five digit number: "); 
string userInput = Console.ReadLine(); 

for (int i = 0; i < userInput.Length; i++) { 
char[] ip = userInput.ToCharArray(); 
Console.Write(ip[i] + " "); 
} 
Console.ReadKey(); 

或

Console.WriteLine("Please enter in a five digit number: "); 
string userInput = Console.ReadLine(); 

foreach(char c in userInput) { 
Console.Write(c + " "); 
} 
Console.Read(); 

Answer 3

static void Main() 
{ 
    Console.Write("Please enter in a five digit number: "); 
    Console.WriteLine(string.Join(" ", Console.ReadLine().ToCharArray())); 
    Console.Read(); 
} 

Answer 4

 Console.WriteLine("Please enter in a five digit number: "); 
     string num = Console.ReadLine(); 
     string result = ""; 
     foreach (char n in num) 
     { 
      result += n + " "; 
     } 
     Console.Write(result); 
     Console.ReadKey();
