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 = 5
Output: SPRING

Input: M = 1
Output: 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 <bits/stdc++.h>
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;
}
