Write a C program to input a number and find square root of the given number. How to find square root of a number in C programming using inbuilt `sqrt()`

function. How to use predefined `sqrt()`

function to find square root in C program.

**Example**

**Input**

Enter any number: 9

**Output**

Square root of 9 = 3

## Required knowledge

Data types, Basic input/output

## Program to find square root of any number

```
/**
* C program to find square root of a number
*/
#include <stdio.h>
#include <math.h>
int main()
{
double num, root;
/* Input a number from user */
printf("Enter any number to find square root: ");
scanf("%lf", &num);
/* Calculate square root of num */
root = sqrt(num);
/* Print the resultant value */
printf("Square root of %.2lf = %.2lf", num, root);
return 0;
}
```

Output

Enter any number to find square root: 144 Square root of 144.00 = 12.00

Happy coding 😉
