//program to convert binary no. to hexadecimal number system.

#include<stdio.h>

#include<conio.h>

void main()

{

   

    long int binary_Number,hexadecimalNumber=0,j=1,remainder;

   

    printf("Enter any number any binary number: ");

    scanf("%ld",&binary_Number);

   

    while(binary_Number!=0)

{

    remainder=binary_Number%10;

    hexadecimalNumber=hexadecimalNumber+remainder*j;

        j=j*2;

        binary_Number=binary_Number/10;

      }

    printf("Equivalent hexadecimal value: %lX",hexadecimalNumber);

    getch();

}

-----------------------------------------------------------------------

logics in mind:-

->we have to input a binary number, say 111
->we make group of 3 bits from right side, and for this, we use 

hexdecimalNumber=hexadecimalNumber+remainder*j;
