C Program to convert Binary to Octal

Program:

 #include<stdio.h>
 #include<math.h>
 int main()
 {
     int bin, dec=0, oct=0, i=0;
     printf("Enter Binary Number: ");
     scanf("%d", &bin);


     while(bin != 0)
     {
         dec += (bin%10) * pow(2,i);
         bin /= 10;
         i++;
     }

     i=1;
     while(dec != 0)
     {
         oct += (dec%8) * i;
         dec /= 8; 
         i *= 10;
     }

     printf("Octal Value = %d",oct);
     return 0;
 }

Output:

Enter Binary Number: 1011
Octal Value = 13
