#include <stdio.h>
#include <conio.h>

int main()
{
    long int binaryval, hexadecimalval = 0, i = 1, remainder;

    printf("Enter the binary number: ");
    scanf("%ld", &binaryval);
    while (binaryval != 0)
    {
        remainder = binaryval % 10;
        hexadecimalval = hexadecimalval + remainder * i;
        i = i * 2;
        binaryval = binaryval / 10;
    }
    printf("Equivalent hexadecimal value: %lX", hexadecimalval);

    getch();
    return 0;
}
