#include<stdio.h>

int main(){

   

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

   

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

    scanf("%ld",&binaryNumber);

   

    while(binaryNumber!=0){

    remainder=binaryNumber%10;

    hexadecimalNumber=hexadecimalNumber+remainder*j;

        j=j*2;

        binaryNumber=binaryNumber/10;

      }

   

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

    return 0;

}

Sample output:

Enter any number any binary number: 1101
