Q)Write a C program to convert the BINARY NUMBER to OCTAL NUMBER

Sol)

#include<stdio.h>

int main( )

{

    long int binary_no, octal_no=0, j=1, rem;

   

    printf("Enter any Binary number: " ) ;

    scanf("%ld", &binary_no) ;

    while(binary_no!=0)

       {

              rem=binary_no%10 ;

              octal_no=octal_no+rem*j ;

              j=j*2;

              binary_no=binary_no/10 ;

       }

     printf("Equivalent octal value: %ld", octal_no) ;

     return 0;

}
