days in a year c++

To calculate the number of days in a year using C++, you can follow these steps:

  1. Declare and initialize variables: Start by declaring and initializing two variables: "year" and "days". The "year" variable will store the year for which you want to calculate the number of days, and the "days" variable will store the result.

cpp int year = 2023; // Replace 2023 with the desired year int days = 0;

  1. Check for leap year: Determine if the given year is a leap year or not. A leap year has 366 days instead of the usual 365 days. To check if a year is a leap year, you need to consider the following conditions:

  2. If the year is divisible by 4, it is a potential leap year.

  3. If the year is divisible by 100, it is not a leap year, unless it is also divisible by 400.

cpp if ((year % 4 == 0 && year % 100 != 0) || year % 400 == 0) { // Leap year days = 366; } else { // Non-leap year days = 365; }

  1. Output the result: Finally, output the calculated number of days using the "cout" statement.

cpp cout << "Number of days in " << year << ": " << days << endl;

Here's the complete code:

#include <iostream>
using namespace std;

int main() {
    int year = 2023; // Replace 2023 with the desired year
    int days = 0;

    if ((year % 4 == 0 && year % 100 != 0) || year % 400 == 0) {
        days = 366;
    } else {
        days = 365;
    }

    cout << "Number of days in " << year << ": " << days << endl;

    return 0;
}

This code will output the number of days in the specified year. Remember to replace the value of the "year" variable with the desired year for accurate results.
