program to print number of days in a month using switch case

Write a C program to input month number and print total number of days in month using switch...case. C program to find total number of days in a month using switch...case.

Total days in a month is given by below table.
Month                                                                         	Total days

April, June, September, November                                	30 days

Step by step descriptive logic to print number of days in a month using switch...case.

    Input month number from user. Store it in some variable say month.
    Switch the value of month i.e. switch(month) and match with cases.
    There can be 12 possible values (choices) of month i.e. from 1 to 12. Hence, write 12 cases inside switch and one default case as else block.
    Print 31 for case 1, 3, 5, 7, 8, 10, 12.
    Print 30 for case 4, 6, 9, 11.
    Print 28/29 for case 2.
    Print invalid input for default case.

#include <stdio.h>

int main()
{
    int month;

    /* Input month number from user */
    printf("Enter month number(1-12): ");
    scanf("%d", &month);

    switch(month)
    {
        case 1: 
            printf("31 days");
            break;
        case 2: 
            printf("28/29 days");
            break;
        case 3: 
            printf("31 days");
            break;
        case 4: 
            printf("30 days");
            break;
        case 5: 
            printf("31 days");
            break;
        case 6: 
            printf("30 days");
            break;
        case 7: 
            printf("31 days");
            break;
        case 8: 
            printf("31 days");
            break;
        case 9: 
            printf("30 days");
            break;
        case 10: 
            printf("31 days");
            break;
        case 11: 
            printf("30 days");
            break;
        case 12: 
            printf("31 days");
            break;
        default: 
            printf("Invalid input! Please enter month number between 1-12");

    }

    return 0;
