## Square Root of a Number

The square root of a number is a value that, when multiplied by itself, gives the original number. For Example- The square root of 64 is 8 because 8×8 is 64.

## C Program for Calculating Square Root

Let’s write a C program that calculates the square root of a given number.

```
#include <stdio.h>
#include <math.h>
void main()
{
float number, squareroot;
printf("Enter the number ");
scanf("%f", &number);
if (number<0)
{
printf("Error: Please enter a non negative number");
return;
}
squareroot = sqrt(number);
printf("The square root of %f is %f\n", number, squareroot);
}
```

### Output

The above program calculates the square root of a given number by using the `sqrt()`

function from `math.h `

library.

*Happy Coding*
