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.

Print Even Numbers Between Two Numbers in C

Print Even Numbers Between Two Numbers in C

✅ C Program to Print Even Numbers Between Two Numbers

#include <stdio.h>

int main() {
    int start, end;

    // Input the range
    printf("Enter the starting number: ");
    scanf("%d", &start);
    printf("Enter the ending number: ");
    scanf("%d", &end);

    // Validate input
    if (start > end) {
        printf("Invalid input! Starting number must be less than or equal to ending number.\n");
        return 1;
    }

    // Print even numbers
    printf("\nEven numbers between %d and %d are:\n", start, end);
    for (int i = start; i <= end; i++) {
        if (i % 2 == 0) {
            printf("%d ", i);
        }
    }

    printf("\n");
    return 0;
}

📘 Explanation:

✅ This program takes a range (start and end) from the user.
✅ It uses a for loop to iterate between the numbers.
✅ It checks for i % 2 == 0 to print only even numbers.
✅ Invalid input is handled if start > end.
✅ The output is displayed on the same line for clarity.

🧾 Sample Output:

Enter the starting number: 10
Enter the ending number: 20

Even numbers between 10 and 20 are:
10 12 14 16 18 20
