Understanding Leap Year Check

A leap year is divisible by 4, but not by 100, unless it's also divisible by 400. The condition uses logical operators: (year % 4 == 0 && year % 100 != 0) checks for regular leap years, and (year % 400 == 0) handles century years.

Note: To write and run C++ programs, you need to set up the local environment on your computer. Refer to the complete article Setting up C++ Development Environment. If you do not want to set up the local environment on your computer, you can also use online IDE to write and run your C++ programs.
