To find the given no. is perfect** square (or) not**

### Program:

#include<stdio.h> #include<conio.h> #include<math.h> void main() { int m, n ; float p ; clrscr() ; printf("Enter a number : ") ; scanf("%d", &n) ; p = sqrt(n) ; m = p ; if (p == m) printf("\n%d is a perfect square", n) ; else printf("\n%d is not a perfect square", n) ; getch() ; }

### Output:

**Case: 1**

```
Enter a number : 81
81 is a perfect square
```

**Case: 2**

```
Enter a number : 12
