Program to Input Weekday Number and Print the Weekday in C#

Last Updated : 22 Jun, 2020

C# Program to print weekday name from a given weekday number (0-6). A switch statement allows checking a value with a list of values or cases.

Weekday number is the number whose value from 0 to 6. 0 is for “Sunday”, 1 is for “Monday”, 2 is for “Tuesday”, 3 is for “Wednesday”, 4 is for “Thursday”, 5 is for “Friday” and 6 is for “Saturday”. This will check with a switch statement.

Example:

Input: 2

Output: Tuesday

Input: 6

Output: Saturday

Example 1:

// C# program to input weekday number  
// print the weekday 
using System; 
using System.IO; 
using System.Text; 
   
namespace Geeks 
{ 
    class GFG 
    { 
        // Main Method  
        static void Main(string[] args) 
        { 
            int weekday; 
   
            // input weekday number 
            Console.Write("Enter weekday number (0-6): "); 
            weekday = Convert.ToInt32(Console.ReadLine()); 
   
            // Using switch case to validate 
            switch (weekday) 
            { 
                case 0: 
                    Console.WriteLine("It is SUNDAY"); 
                    break; 
                case 1: 
                    Console.WriteLine("It is MONDAY"); 
                    break; 
                case 2: 
                    Console.WriteLine("It is TUESDAY"); 
                    break; 
                case 3: 
                    Console.WriteLine("It is WEDNESDAY"); 
                    break; 
                case 4: 
                    Console.WriteLine("It is THURSDAY"); 
                    break; 
                case 5: 
                    Console.WriteLine("It is FRIDAY"); 
                    break; 
                case 6: 
                    Console.WriteLine("It is SATURDAY"); 
                    break; 
               
            } 
   
               
        } 
    } 
} 

Output: When we enter number between (0-6).

Enter weekday number (0-6): It is WEDNESDAY

Example 2:

// C# program to input weekday number  
// print the weekday 
using System; 
using System.IO; 
using System.Text; 
   
namespace Geeks 
{ 
    class GFG 
    { 
        // Main Method  
        static void Main(string[] args) 
        { 
            int weekday; 
   
            // input weekday number 
            Console.Write("Enter weekday number (0-6): "); 
            weekday = Convert.ToInt32(Console.ReadLine()); 
   
            // Using switch case to validate 
            switch (weekday) 
            { 
                case 0: 
                    Console.WriteLine("It is SUNDAY"); 
                    break; 
                case 1: 
                    Console.WriteLine("It is MONDAY"); 
                    break; 
                case 2: 
                    Console.WriteLine("It is TUESDAY"); 
                    break; 
                case 3: 
                    Console.WriteLine("It is WEDNESDAY"); 
                    break; 
                case 4: 
                    Console.WriteLine("It is THURSDAY"); 
                    break; 
                case 5: 
                    Console.WriteLine("It is FRIDAY"); 
                    break; 
                case 6: 
                    Console.WriteLine("It is SATURDAY"); 
                    break; 
                   
                // if no case value is matched 
                default: 
                    Console.WriteLine("It is wrong input"); 
                    break; 
            } 
   
               
        } 
    } 
} 

Output: When we enter number beyond the range from (0-6).

Enter weekday number (0-6): It is wrong input
