[c-prog] Re: binary to decimal

[sharma.anandd]

U have not learnt function yet ?
I can help u to learn function, if u give me your email id.

This program can also be solved without using function.
but here m using two loops one for counting digits int binary number and other 
for converting to decimal.

here is the solution.

//Program to convert a binary number to its equivalent decimal number
#include<stdio.h>
#include<conio.h>
#include<math.h>
int main()
{
 int count_digits(int);
 int num,num1,n=0,R,r,dec=0;
 clrscr();
 printf("\nEnter a number in binary form : ");
 scanf("%d",&num);
 num1=num;
 while(num1)  //loop for counting the digits
 {
 num1/=10;
 n++;
 }
 while(num)    //loop for converting the binary number into decimal
 {
  r=num%10;
  R=r*pow(2,--n);
  dec+=R;
  num=num/10;
 }
printf("\nDecimal : %d", dec);
getch();
return 0;
}
