C# program to get the day number as input and print the weekday using switch case:
In this post, we will learn how to use a switch case in C#. The program will take one number as input from the user and it will print the day name using a switch block.
For example, if the user enters 1, it will print Monday, for 2 Tuesday etc. For an invalid input, i.e. if it is not in between 1 to 7, it will print a message that the input is invalid.
Let’s write down the program:
C# program to print the weekday using switch case:
Below is the complete C# program:
using System;
public class Program
{
public static void Main()
{
int day;
Console.WriteLine("Enter the week day number : ");
day = Convert.ToInt32(Console.ReadLine());
switch(day){
case 1:
Console.WriteLine("Monday");
break;
case 2:
Console.WriteLine("Tuesday");
break;
case 3:
Console.WriteLine("Wednesday");
break;
case 4:
Console.WriteLine("Thursday");
break;
case 5:
Console.WriteLine("Friday");
break;
case 6:
Console.WriteLine("Saturday");
break;
case 7:
Console.WriteLine("Sunday");
break;
default:
Console.WriteLine("Invalid input");
break;
}
}
}Explanation:
Here,
- It is asking the user to enter the week day and storing that value in the variable day.
- Based on the value of day, it moves to a case block and prints the message.
- For any invalid value, i.e. if the number is not in 1,2,3,4,5,6,7, it moves to the default block and prints that the input is invalid.
Sample output:
It will print output as like below:
Enter the week day number :
4
Thursday
Enter the week day number :
99
Invalid input
