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.

✅ Binary to Hexadecimal Conversion in C

#include<stdio.h>
int main( )
{
    int num, hexa = 0, remainder, j = 1;
    printf("Enter the binary number:\n");
    scanf("%d", &num);
    while(num != 0)
    {
        remainder = num % 10;
        hexa = hexa + remainder * j;
        j = j * 2;
        num = num / 10;
    }
    printf("The hexadecimal value is %X\n", hexa);
}

📘 Explanation:

This C program converts a binary number (input as an integer) to its hexadecimal equivalent. The binary number is first converted to its decimal form manually using bit-weight multiplication (base 2 logic). The resulting decimal is then printed in hexadecimal using the format specifier %X.

🧾 Sample Output:

Enter the binary number:
1010
The hexadecimal value is A
