Program to convert a decimal number to binary number.

void Binary(int n)
{
 int digit[100], int index = 0;
 while(n)
{
 n!= 0 or n > 0
  digit[index++] = n%2;
  n /= 2;
 }
 for(int i = index-1; i>=0; i--)
{
  printf("%d",digit[i]);
 }
}

int main()
{
 int n;
 scanf("%d",&n);
 Binary(n);
 return 0;
}
