sqrt function in C programming language

In this tutorial, we will discuss sqrt function in C programming language

Description

description of sqrt function in C programming language:

The sqrt() function in C programming language returns the square root value

sqrt() : In C Programming Language, this is used to find square root of the given value

Declaration

declaration sqrt() min C programming language

double sqrt (double x);

parameters or Argument

parameter of sqrt() in C language is:

x- x is the parameter or argument of this function for calculating the square root of x

Returns

when you pass a value for x, this function returns the square root value of x

Required Header

In thic Language, the required header file for sqrt() is

#include <math.h>

Example

The following example shows the usage of sqrt() function

sqrt function in C

Program 1

#include <stdio.h>
#include <math.h>
int main()
{

    printf("sqrt value of 3 is %f\n",sqrt(3));
    printf("sqrt value of 4 is %f\n",sqrt(4));
    printf("sqrt value of 6 is %f\n",sqrt(6));
    getch();
    return 0;
}

When the above program is compiled, it will produce the following result

sqrt value of 3 is 1.732051

sqrt value of 4 is 2.000000

sqrt value of 6 is 2.449490

Program 2

#include <stdio.h>
#include <math.h>
int main()
{
    //define temporary variable
    double val1;
    double result;
    printf("Enter the number for val1 :");
    //get input from user
    scanf("%lf",&val1);
    //calculate sqrt
    result=sqrt(val1);
    //Display sqrt value
    printf("sqrt value is: %lf\n",result);
getch();
    return 0;
}

When the above program is compiled, it will produce the following result

Enter the number for val1: 25

sqrt value is: 5.000000
