#include<iostream.h>
#include<conio.h>
void main()
{
clrscr();
long int decnum, rem, quot;
int binnum[100], i=1, j;
cout<<"Enter any decimal number : ";
cin>>decnum;
quot=decnum;
while(quot!=0)
{
binnum[i++]=quot%2;
quot=quot/2;
}
cout<<"Equivalent binary value of "<<decnum<<" :\n";
for(j=i-1; j>0; j--)
{
cout<<binnum[j];
}
getch();
}
Output
Enter any decimal number :20
Equivalent binary value of 20 :
10100
Enter any decimal number :8
Equivalent binary value of 8 :
1000
