Program to calculate square root c

0 votes

Making a C++ application to determine a number's square root. 

The built-in arithmetic operator "sqrt" is not used in this application. 

There are two variables: one for the user-inputted integer and the other for the number's square root. 

This software does not function very well, and I am certain that there is a more effective method to accomplish it:

Here is my full code:

#include <iostream>
using namespace std;

int main(){
  int squareroot = 0;
  int number;

  cout << "enter a number sp that i can calculate its squareroot" << endl;

  cin >> number;

  while (squareroot * squareroot != number){

      squareroot+=0.1;

}
cout << "the square root is" << squareroot << endl;
return 0;
 }

I'm sure there must be a better approach. 

help please 

I looked via Google, but since I'm still learning, I don't comprehend the sophisticated programmes there.

I appreciate it.

What is the best way to use a HashMap in C++?

The ordered and unordered map containers (std::map and std::unordered map) are included in the standard library.  The items in an ordered map are sorted by key, and insert and access are in O (log n).  For ordered maps, the standard library often use red black trees.  However, this is only an implementation detail.  Insert and access are in O in an unordered map (1).  It is simply another term for a hashtable. An illustration using (ordered) std::map: #include <map> #include <iostream> #include <cassert> int main(int argc, char ...READ MORE
