Merge Sort in C++

  Merge Sort in C++ Introduction Merge Sort is a popular sorting algorithm that follows the Divide and Conquer approach. It divides an array into smaller subarrays, recursively sorts those subarrays, and finally merges the sorted subarrays to produce a completely sorted array. In this tutorial, we will learn how to implement Merge Sort in C++ . The program divides the array into two halves using the mid index, recursively sorts both halves, and then combines them using the merge() function. Merge Sort has a time complexity of O(n log n) in the best, average, and worst cases.

C Program to Check Leap Year

C Program to Check Leap Year

✅ C Program to Check Leap Year


#include <stdio.h>

int main()
{
    int year;

    printf("Enter a year: ");
    scanf("%d", &year);

    if ((year % 400 == 0) || (year % 4 == 0 && year % 100 != 0))
        printf("%d is a Leap Year\n", year);
    else
        printf("%d is NOT a Leap Year\n", year);

    return 0;
}
  

๐Ÿ“˜ Explanation:

This C program checks whether a given year is a leap year or not.

A year is a leap year if:

  • It is divisible by 400, OR
  • It is divisible by 4 but not divisible by 100

These conditions are checked using logical operators and modulus (%) operator.

๐Ÿงพ Sample Output:

Enter a year:
2024
2024 is a Leap Year
