Program to convert a binary number to decimal number.

  If you have studied number system then you must have heard about the different

  types of numbers like decimal, binary , Octal, hexadecimal these are just number

  system in which codes are written in computer like computer understand binary

  and color we use in computer has their own hexadecimal values.

  So, through this program we will be doing conversation between Binary number

  to Decimal number.  

 Program

  #include<stdio.h>

  #include<math.h>

   void main()

   {

    int n,pow=1,rem,sum=0;

    printf("Enter the binary number :");

    scanf("%d",&n);

    for(n=n ; n>0 ; )

       {

         rem=n%10;

         sum=sum+rem*pow;

         pow=pow*2;

         n=n/10;

        }

      printf("%d is the decimal conversion",sum);

    }

  Output:

 

 Here, Binary number entered is 11010 and output is 26 which is the decimal conversion of the binary number.
