Pow() in c

---

---

The C library sqrt() function of type double accept the variable x(double) as parameter to return the result of square root. The square of a number is obtained by multiplying the number by itself.

Syntax

Following is the syntax of the C library function sqrt() −

double sqrt(double x)

Parameters

This function accepts only a single parameters −

• x − This is the floating point value.

Return Value

This function returns the square root of x.

Example 1

Following is the C library program that illustrates the usage of sqrt() function.

#include <stdio.h> #include <math.h> int main () { printf("Square root of %lf is %lf\n", 4.0, sqrt(4.0) ); printf("Square root of %lf is %lf\n", 5.0, sqrt(5.0) ); return(0); }

Output

On execution of above code, we get the following result −

Square root of 4.000000 is 2.000000 Square root of 5.000000 is 2.236068

Example 2

Below the example demonstrate the usage of sqrt() function in a loop.

This program involve the table of square roots ranges between 0-10.
