Program to find the square root of a number using Newton Raphson Method.

#include<iostream>
using namespace std;
float absolute(float s){
if(s<0){
s=-s;
}
return s;
}
float sqrt(float n){
int difference=0.0001;
int guess=1;
while(absolute(guess*guess-n)>difference){
guess=(n/guess+guess)/2;
}
return guess;
}
int main(){
int number;
float root;
cout<<”Enter the number of N:”;
cin>>number;
root=sqrt(number);
cout<<”\nRoot : “<<root;
return 0;
}
