Write a C++ program calculates the following equation for entered numbers (n, x). 1+1/1+1/1+(sqrt x)..................n terms

3:12 AM

Exercise 4)
Write a C++ program and call it series2.cpp which receives two numbers from input (n, x) and calculates the following equation for entered numbers (n, x).
1+1/1+1/1+(sqrt x)..................n terms

Solution-


#include<iostream>
#include<cmath>

using namespace std;


int main()
{
//-------defining variables and initializing them-------------
double n,x,i,ans,ans1;
char redo;
//--------Printing my name on screen----------------
cout<<"Welcome to the n term series program written by Your Name"<<endl;
cout<<"***************************************************************"<<endl;
cout<<endl<<endl<<endl;
//--here do loop is used so that the program can be used more then one time
//without exiting the run screen---------------------------
do
{
//----receiving the variables from input--------------

cout<<" Please enter two numbers to apply your requested operation"<<endl;
cout<<"enter the value of n:";
cin>>n;
cout<<"enter the value of x:" ;
cin>>x;
cout<<endl;
// initialising for loop
for(i=0;i<=n;i++)
{
// the desired expression has the below formulae
//when u enter n=0 and x=0 the ans will be 1.5 because our series starts from(1+1/ans1)
ans1= (1+1/(1+sqrt(x)));
ans=(1+1/ans1);
}
//------- printing the results on screen-----------
cout<<"the ans of this series="<<ans<<endl;
//cout<<ans1;


cout<<endl;
//----now once again the program will ask the user if want to continue or not
cout<<"enter y or Y to continue:";
cin>>redo;
cout<<endl<<endl;

}
while(redo=='y'||redo=='Y');

system("pause");
return 0;

}
