//it is to convert Binary to decimal;


#include<stdio.h>
#include<conio.h>
#include<math.h>
void main()
{
long int a[20],i,n,count=0,b[20],c[20],sum=0;
printf("ENter the number in binary form=\t");
scanf("%ld",&n); // Get a binary number
from the user
for (i=0;n>=1;i++)
{
a[i]=n%10;
n=n/10; // Loop To reverse the number And put
all reversed numbers in arry a[i]
count=count + 1; // count to count the number of times
this loop runs
}
for (i=0;i<=count-1;i++) // count -1 condition is used to
run the loop till the previous loop run
{
b[i]=pow(2,i); // This is to raise the power of 2 to no
of times previous loop runned.
}
for (i=0;i<=count-1;i++)
{
c[i]=a[i] * b[i]; // Multiply a[i] or reveresed binary
no with b[i] or increasing pow of 2 to count-1
sum=sum +c[i]; // it is to add the c[i] elements with
each other n put into sum variable.
}
printf("Decimal form =%ld",sum); // printing the sum to get
the decimal form
getch();
}
// Hope it solves your problem, ANy more assistance
