using namespace std;
int main()
{
int dec_num, rem, quot, i=1, j;
int bin_num[100];
cout << "\n\n Convert a decimal number to binary number:\n";
cout << "---------------------------------------------------\n";
cout << " Input a decimal number: ";
cin>> dec_num;
quot = dec_num;
while(quot != 0)
{
bin_num[i++] = quot%2;
quot = quot/2;
}
cout<<" The binary number is: ";
for(j=i-1; j>0; j--)
{
cout<<bin_num[j];
}
cout<<("\n");
