# Print the season name of the year based on the month number

Given the month number M, the task is to print the season name of the year based on the month number.
Examples:

`Input: M = 5Output: SPRINGInput: M = 1Output: WINTER`

Approach:

• There are 4 main seasons in a year, that is, Summer, Autumn, Winter and Spring.
• The winter months are in December, January and February.
• The spring months in March, April and May.
• The summer months in June, July and August.
• And the autumn months in September, October and November.
• So map the month to the particular season respectively and print it.

Below is the implementation of the above approach:

## C++

 `// C++ program to print the season` `// name based on the month number` `#include ` `using` `namespace` `std;`   `void` `findSeason(``int` `M)` `{`   `    ``// Checks out the season according` `    ``// to the month number entered by the user` `    ``switch` `(M) ` `    ``{` `        ``case` `12:` `        ``case` `1:` `        ``case` `2:` `            ``cout << (``"\nWINTER"``);` `            ``break``;` `        ``case` `3:` `        ``case` `4:` `        ``case` `5:` `            ``cout << (``"\nSPRING"``);` `            ``break``;` `        ``case` `6:` `        ``case` `7:` `        ``case` `8:` `            ``cout << (``"\nSUMMER"``);` `            ``break``;` `        ``case` `9:` `        ``case` `10:` `        ``case` `11:` `            ``cout << (``"\nAUTUMN"``);` `            ``break``;` `        ``default``:` `        `  `            ``// Handles the condition if number entered` `            ``// is not among the valid 12 months` `            ``cout << (``"\nInvalid Month number"``);` `            ``break``;` `    ``}` `}`   `// Driver code` `int` `main()` `{` `    ``int` `M = 5;` `    ``cout << ``"For Month number: "` `<< M;` `    ``findSeason(M);`   `    ``M = 10;` `    ``cout << ``"\nFor Month number: "` `<< M;` `    ``findSeason(M);` `    ``return` `0;` `}`   `// This code is contributed by Rajput-Ji`

### Dictionary Mapping

We can create a dictionary to map the month number to its corresponding season. Then we can simply retrieve the value from the dictionary using the input month number.

Steps:

• Create a dictionary with the keys as month numbers and the values as corresponding seasons.
• Take the input month number from the user.
• Retrieve the value from the dictionary using the input month number.
• Print the season name.

## C++

 `#include ` `#include ` `#include `   `int` `main() ` `{` `  `  `    ``// Create an unordered map that maps month numbers to season names.` `    ``std::unordered_map<``int``, std::string> seasons {` `        ``{1, ``"WINTER"``},` `        ``{2, ``"WINTER"``},` `        ``{3, ``"SPRING"``},` `        ``{4, ``"SPRING"``},` `        ``{5, ``"SPRING"``},` `        ``{6, ``"SUMMER"``},` `        ``{7, ``"SUMMER"``},` `        ``{8, ``"SUMMER"``},` `        ``{9, ``"FALL"``},` `        ``{10, ``"FALL"``},` `        ``{11, ``"FALL"``},` `        ``{12, ``"WINTER"``}` `    ``};`   `    ``// Set the month number to check.` `    ``int` `M = 1;`   `    ``// Get the season name for the given month number.` `    ``std::string season = seasons[M];`   `    ``// Print the season name to the console.` `    ``std::cout << season << std::endl;`   `    ``return` `0;` `}`

## Java

 `import` `java.util.HashMap;`   `public` `class` `GFG {` `    ``public` `static` `void` `main(String[] args) {`   `        ``// Create a HashMap that maps month numbers to season names.` `        ``HashMap seasons = ``new` `HashMap<>();` `        ``seasons.put(``1``, ``"WINTER"``);` `        ``seasons.put(``2``, ``"WINTER"``);` `        ``seasons.put(``3``, ``"SPRING"``);` `        ``seasons.put(``4``, ``"SPRING"``);` `        ``seasons.put(``5``, ``"SPRING"``);` `        ``seasons.put(``6``, ``"SUMMER"``);` `        ``seasons.put(``7``, ``"SUMMER"``);` `        ``seasons.put(``8``, ``"SUMMER"``);` `        ``seasons.put(``9``, ``"FALL"``);` `        ``seasons.put(``10``, ``"FALL"``);` `        ``seasons.put(``11``, ``"FALL"``);` `        ``seasons.put(``12``, ``"WINTER"``);`   `        ``// Set the month number to check.` `        ``int` `M = ``1``;`   `        ``// Get the season name for the given month number.` `        ``String season = seasons.get(M);`   `        ``// Print the season name to the console.` `        ``System.out.println(season);` `    ``}` `}`

## Python3

 `# Step 1` `seasons ``=` `{` `    ``1``: ``'WINTER'``,` `    ``2``: ``'WINTER'``,` `    ``3``: ``'SPRING'``,` `    ``4``: ``'SPRING'``,` `    ``5``: ``'SPRING'``,` `    ``6``: ``'SUMMER'``,` `    ``7``: ``'SUMMER'``,` `    ``8``: ``'SUMMER'``,` `    ``9``: ``'FALL'``,` `    ``10``: ``'FALL'``,` `    ``11``: ``'FALL'``,` `    ``12``: ``'WINTER'` `}`   `# Step 2` `M ``=` `1`   `# Step 3` `season ``=` `seasons.get(M)`   `# Step 4` `print``(season)`

## C#

 `using` `System;` `using` `System.Collections.Generic;`   `class` `Program {` `    ``static` `void` `Main() {` `        ``// Create a dictionary that maps month numbers to season names.` `        ``Dictionary<``int``, ``string``> seasons = ``new` `Dictionary<``int``, ``string``>() {` `            ``{1, ``"WINTER"``},` `            ``{2, ``"WINTER"``},` `            ``{3, ``"SPRING"``},` `            ``{4, ``"SPRING"``},` `            ``{5, ``"SPRING"``},` `            ``{6, ``"SUMMER"``},` `            ``{7, ``"SUMMER"``},` `            ``{8, ``"SUMMER"``},` `            ``{9, ``"FALL"``},` `            ``{10, ``"FALL"``},` `            ``{11, ``"FALL"``},` `            ``{12, ``"WINTER"``}` `        ``};`   `        ``// Set the month number to check.` `        ``int` `M = 1;`   `        ``// Get the season name for the given month number.` `        ``string` `season = seasons[M];`   `        ``// Print the season name to the console.` `        ``Console.WriteLine(season);` `    ``}` `}`

## Javascript

 `// Step 1` `const seasons = {` `1: ``'WINTER'``,` `2: ``'WINTER'``,` `3: ``'SPRING'``,` `4: ``'SPRING'``,` `5: ``'SPRING'``,` `6: ``'SUMMER'``,` `7: ``'SUMMER'``,` `8: ``'SUMMER'``,` `9: ``'FALL'``,` `10: ``'FALL'``,` `11: ``'FALL'``,` `12: ``'WINTER'` `};`   `// Step 2` `const M = 1;`   `// Step 3` `const season = seasons[M];`   `// Step 4` `console.log(season);`

Output

```WINTER
