# Write a c program to find square root of any number

Math sqrt function but things can be tricky questionif interviewer will ask you to write your own sqrt function during programming interviewswell its not that easy to write sqrt function which can operatre on double but one trick I use to remember the concept that square of square root must be either less than or equal to number, you can use that concept to write your own sqrt method in any programming language including Java.

To summarize, some advantages of black box abstraction and top down refinement in algorithm design and implementation include: For a given function f xhow do we find the place where the curve crosses zero?

Another Java coding questions which is very popular and related to programming exercise is writing Java program to find prime numbersif you are going to appear in Java interviews then its worth looking. Anyway here we will see Java program for finding square root using API method, package test.

You just need to pass a double value and it returns a double which is square root of number you passed. If we could somehow use the general "direction" of the curve to guide us, it could lead us to a better guess. If you are familiar with Java API then writing a Java program which can find square root of number using java.

Given the slope of the line, how do we compute the new guess? Then we do it again: Note that this also helps us stop earlier on large square roots.

But what if we want to take cube roots or fourth roots? But which guesses do we try in order to reach the solution quickly? So the question becomes more general: If our solution is only within. How to find Square root of a number in Java As I said its easy to calculate square root using java.

Math class is not difficult.

Maybe we can be more clever about closeEnough. The derivative provides us with exactly that. In next section we will see complete code example of finding square root of a number from Java program.

We could solve this by guessing values as before and trying better guesses until we reach the solution. Given these facts, what might we do? So two details remain: We could print the guess each time test is called to see how it converges.

Suppose we modify closeEnough a, b to return true iff a and b differ by a small percentage. For example, suppose we try sqrt.write a C++ program to find the area of a square, input the length of the side, and output your answer to the screen.

Java program to find square root of number - Example Code Java program for square root or a number in Java How to write Java program to find square root of a number is common Java programming exercise which many institute use in there Java course along with Java program to print Fibonacci series and How to find Armstrong.

How to find the cube of a number using C, C++ program. It's a basic programming question in which a number is input by a user and our program calculate it's cube. How to Calculate Cube of a Number Suppose a user has entered 5.

Cube of 5 is: 5 * 5 * 5 (). Similarly, We can calculate cube of any number by multiplying the same number three. A square root is the number that, when multiplied by itself, equals the original number.

Sqrt is a slower computation. It can be cached for a performance boost.`Example.` The killarney10mile.com method is called with a double argument. Can you write a c program to find the square root of a number without using sqrt() function or other predefined functions.

This has been a great challenge in interview as you can do it by using newtons algorithm which you should previously know for implementing. However here are mentioned some useful methods to solve this question.

Recursive Algorithms: Square Root The discussion of finding square roots seems academic in some sense because there's already a builtin killarney10mile.com method. But what if we want to take cube roots or fourth roots? Now let's write the code: import csterminal.*; public class RootFinder { int n.
