In this program, You will learn how to find perfect square numbers between 1 to n in c.

`Some list of perfect square numbers is: 1 4 9 16 25 36 49 64`

## Example: How to find perfect square numbers between 1 to n in c.

```
#include<stdio.h>
#include<math.h>
int main() {
int n, i, root;
printf("Enter a number:");
scanf("%d", & n);
for (i = 1; i <= n; i++) {
root = sqrt(i);
root = root * root;
if (i == root) {
printf("\ni = %d", i);
}
}
return 0;
}
```

#### Output:

```
Enter a number:50
i = 1
i = 4
i = 9
i = 16
i = 25
i = 36
i = 49
```
