Decimal to Binary Conversion

#include<stdio.h>

#include<conio.h>

#include<math.h>

void main()

{

int no,r,sum=0,i=0;

clrscr();

printf(“\nenter the number\n”);

scanf(“%d”,&no);

while(no>0)

{

r=no%2;

sum=sum+pow(10,i)*r;

no=no/2;

i++;

}

printf(“\nthe binary value is %d”,sum);

getch();

}

Output:

enter the number

8

the binary value is 1000
