In this tutorial, you will learn how to write a program to print the total number of days in a given month. To achieve this we will use the switch statement.
Our problem statement :
Every month in a calendar year has a different number of days. We are taking a user input between 1 to 12 and showing a fixed output based on the entered value.
Example :
Input: 5
Output: May has 31 days.
When the user input matches the correct cases of the switch statement it executes that block. Input beyond the cases goes into the default block.
#include <stdio.h>
int main() {
int month;
printf("Enter the month number (1-12): ");
scanf("%d", &month);
switch (month) {
case 1:
printf("January has 31 days.\n");
break;
case 2:
printf("February has 28 or 29 days depending on whether it's a leap year.\n");
break;
case 3:
printf("March has 31 days.\n");
break;
case 4:
printf("April has 30 days.\n");
break;
case 5:
printf("May has 31 days.\n");
break;
case 6:
printf("June has 30 days.\n");
break;
case 7:
printf("July has 31 days.\n");
break;
case 8:
printf("August has 31 days.\n");
break;
case 9:
printf("September has 30 days.\n");
break;
case 10:
printf("October has 31 days.\n");
break;
case 11:
printf("November has 30 days.\n");
break;
case 12:
printf("December has 31 days.\n");
break;
default:
printf("Invalid input. Please enter a number between 1 and 12.\n");
break;
}
return 0;
}Output:
Enter the month number (1-12): 6
June has 30 days.
