# Getting the Total Number of Days in a Month Using If-else and Switch Statements in C#

Given a number N, the task is to write a C# program to print the number of days in the Month N.

Examples:

Input: N = 12
Output: 31

Input: N = 2
Output: 28/29

This task can be done using the following approaches:

1. Using if else statement : Appropriate month number is checked and then number of days in a month is print using else if statement. Number of days are follows :

```Month = [1, 3, 5, 7, 8, 10, 12] , Number of days = 31
Month =  , Number of days = 28/29
Month = [4, 6, 9, 11] , Number of days = 30
```

Below is the implementation of the above approach:

Output:

## C#

 `// C# Program to Print Number of Days ` `// in a Month using Else If Statement ` ` `  `using` `System; ` ` `  `public` `class` `GFG{ ` ` `  `    ``// Function to print the Number ` `    ``// of Days in a N ` `    ``static` `void` `PrintNumberofDays(``int` `N)  ` `    ``{ ` `       ``// Check for the Ns ` `        ``if` `(N == 1 || N == 3 || N == 5 || N == 7 ` `          ``|| N == 8 || N == 10 || N == 12) { ` `              ``Console.Write(``"31"``); ` `        ``}  ` `         `  `        ``else` `if` `(N == 4 || N == 6 || N == 9 || ` `               ``N == 11) { ` `               ``Console.Write(``"30"``); ` `        ``}  ` `         `  `        ``else` `if` `(N == 2) { ` `               ``Console.Write(``"28/29"``); ` `        ``} ` `    ``} ` `     `  `    ``// Driver Code ` `    ``static` `public` `void` `Main () ` `    ``{ ` `        ``int` `N = 5; ``// 1 <= N <= 12 ` `        ``PrintNumberofDays(N); ` `    ``} ` `}`

Output:

```31
```

2. Using Switch Condition : Same as Else if , here month number is checked and it is redirected to cases,and then number of days in a month is print. Below is the implementation of the above approach:

## C#

 `// C# Program to Print Number of Days ` `// in a Month using Switch Condition ` ` `  `using` `System; ` ` `  `public` `class` `GFG{ ` ` `  `    ``// Function to print the Number ` `    ``// of Days in a N ` `    ``static` `void` `PrintNumberofDays(``int` `N)  ` `    ``{ ` `        ``// Check for the N ` `        ``switch``(N ) ` `        ``{ ` `            ``case` `1: ` `            ``case` `3: ` `            ``case` `5:      ` `            ``case` `7: ` `            ``case` `8: ` `            ``case` `10: ` `            ``case` `12:              ` `                ``Console.Write(``"31"``); ` `                ``break``; ` `             `  `            ``case` `4:  ` `            ``case` `6: ` `            ``case` `9: ` `            ``case` `11:                  ` `                ``Console.Write(``"30"``);  ` `                ``break``; ` `             `  `            ``case` `2: ` `            ``Console.Write(``"28/29"``); ` `            ``break``; ` `        ``} ` `    ``} ` `     `  `    ``// Driver Code ` `    ``static` `public` `void` `Main () ` `    ``{ ` `        ``int` `N = 5; ``// 1 <= N <= 12 ` `        ``PrintNumberofDays(N); ` `    ``} ` `}`

Output:

```31
```
