Program:

#include <stdio.h>

int main()
{

  int a[20],i,m,n,r;
  printf("\n Enter the decimal Integer  ");

  scanf("%d",&n);
  m=n;

  for(i=0;n>0;i++)
  {
    r=n%2;
    a[i]=r;
    n=n/2;
   }

  printf("\n Binary equivalent of %d is \t",m);

  for(i--;i>=0;i--)
    printf("%d",a[i]);

  return 0;

}

Output:

 Enter the decimal Integer  10

 Binary equivalent of 10 is     1010
