Write a program that prompts the user to input a decimal integer and display its binary equivalent.

```
#include <stdio.h>
int main()
{
int number, n, remainder, binary = 0, place = 1;
printf("Enter a number :");
scanf("%d", &number);
n = number;
while (n > 0)
{
remainder = n % 2;
binary += remainder * place;
place *= 10;
n /= 2;
}
printf("Binary equivalent of %d is %d", number, binary);
return 0;
}
```

Enter a number :12

Binary equivalent of 12 is 1100
