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
