C program to convert binary code to octal -My CS Tutorial

In this tutorial we will learn how to write a program that convert binary number to octal number.

C program code

#include<stdio.h>

#include<conio.h>

void main()

{

 int octalNum[]={0,1,10,11,100,101,110,111};

 long int binary,i,number,temp,octal=0,j=1;

 printf("\n Enter Binary number:\n ");

 scanf("%ld",&binary);

 temp=binary;

 while(temp!=0)

 {

  number=temp%1000;

  for(i=0;i<=7;i++)

  {

   if(octalNum[i]==number)

   {

    octal=octal+(i*j);

   }

  }

  j*=10;

  temp/=1000;

 }

 printf("\n Octal number for given Binary number %ld is %ld\n",binary,octal);

 getch();

}

OUTPUT:

We will enter a binary number.

In this output the value of binary code is 11110

And octal number for this binary number is 36
