Method 1: Printing 2024 Calendar Without Using Libraries
Generic Steps to print 2024 Calendar:
-
Include Minimal Headers (if applicable):
- Include the essential headers for input/output (Note: In some languages like JavaScript, this step may not be needed).
-
Define Function to Print a Month:
- Create a function to print the calendar for a specific month.
-
Implement the
print_month
Function:- Inside the function, use basic logic to print the calendar for the specified month without relying on external libraries.
-
Define Function to Print the Entire Calendar:
-
Create another function to iterate over all months and call the
print_month
function.
-
Create another function to iterate over all months and call the
-
Implement the
print_calendar
Function:-
Inside the function, iterate over all months (1 to 12) and call the
print_month
function.
-
Inside the function, iterate over all months (1 to 12) and call the
-
Main Function:
-
Set the desired year and call the
print_calendar
function in themain
function.
-
Set the desired year and call the
