Please check the following program buddy,
Just save it as .c and run it you got what you want

# include <stdio.h>

void Rec_Dec_To_Bin (int num);

void main ()
{
int num;
int base;

printf ("Enter the decimal number to convert it binary.\n");
scanf ("%d", &num);


printf ("The number in decimal is : %d\n", num);
printf ("\n");

printf ("The %d in binary is : ", num);
Rec_Dec_To_Bin (num);

printf ("\n\n");

}

void Rec_Dec_To_Bin (int num)
{

if (((num / 2) != 0) && (num > 1))
{
Rec_Dec_To_Bin ((num / 2));
}

printf ("%d", (num % 2));

}

scanf("%d",&n);
r=bin(n);
printf("The binary equivalent is:%d",r);
getch();
}
int bin(int x)
{ int k;
if(x==0)
return 0;
k=x%2;
int j=k+(10*bin(x/2));
return j;
