# C Program to Print Number of Days in a Month

How to write a C Program to Print Number of Days in a Month using Else If statement and Switch Condition with examples?. As we all know, the total number of days in :

• January, March, May, August, October, and December = 31 Days
• April, June, September, and November = 30 Days
• February = 28 or 29 Days

## C Program to Print Number of Days in a Month using Else If

This C program will ask the user to enter any number between 1 to 12, where 1 is January, 2 = February, 3 = March,………., and 12 = December.

Based on the user entered integer value, this program will print the number of days in a month. To accomplish this goal, we are using Else If Statement.

/* C Program to Print Number of Days in a Month using Else If Statement */

#include <stdio.h>

int main()
{
int month;
printf(" Please Enter the Month Number 1 to 12 (Consider 1 = January, and 12 = December) :  ");
scanf("%d", &month);

if (month == 1 || month == 3 || month == 5 || month == 7 || month == 8 || month == 10 || month == 12 )
{
printf("\n 31 Days in this Month");
}
else if ( month == 4 || month == 6 || month == 9 || month == 11 )
{
printf("\n 30 Days in this Month");
}
else if ( month == 2 )
{
printf("\n Either 28 or 29 Days in this Month");
}
else
printf("\n Please enter Valid Number between 1 to 12");

return 0;
}

Let me enter the month number as 5

Please Enter the Month Number 1 to 12 (Consider 1 = January, and 12 = December) :  5

31 Days in this Month

Let me enter the month number as 9

Please Enter the Month Number 1 to 12 (Consider 1 = January, and 12 = December) :  9

30 Days in this Month

This time, we will enter the wrong value: 15

Please Enter the Month Number 1 to 12 (Consider 1 = January, and 12 = December) :  15

Please enter Valid Number between 1 to 12

## C Program to return Number of Days in a Month using Switch Condition

It is an ideal approach to deal with multiple C Programming conditions. In this program, we are using the Switch Case approach to print the number of days in a month.

#include <stdio.h>

int main()
{
int month;
printf(" Please Enter the Month Number 1 to 12 (Consider 1 = January, and 12 = December) :  ");
scanf("%d", &month);

switch(month )
{
case 1:
case 3:
case 5:
case 7:
case 8:
case 10:
case 12:
printf("\n 31 Days in this Month");
break;

case 4:
case 6:
case 9:
case 11:
printf("\n 30 Days in this Month");
break;

case 2:
printf("\n Either 28 or 29 Days in this Month");

default:
printf("\n Please enter Valid Number between 1 to 12");
}
return 0;
}
Please Enter the Month Number 1 to 12 (Consider 1 = January, and 12 = December) :  12

31 Days in this Month

Let me try different value

Please Enter the Month Number 1 to 12 (Consider 1 = January, and 12 = December) :  6

30 Days in this Month
