✅ 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
