Series Program in C++

This post contain different series program in c++ language with there code and output. These code are implement using the class in the c++ language.

WAP in C++ To generate a series i.e. 1-x+x^2/2!-x^3/3!+……x^n/n!

The program code for above question in C++ language is as follows:

//To generate a series i.e. 1-x+x^2/2!-x^3/3!+......x^n/n!//
#include<iostream>
#include<math.h>

using namespace std;
class series
{
private:float sum,term;
	int i,j,k,fact,sign;
public:series()
       {
       sum=1.0;
       term=0.0;
       i=j=0;
       fact=1;
       sign=-1;
       }
       double generate(int x,int n);
       ~series()
       {
       }
};
double series::generate(int x,int n)
{
cout<<"1   ";
for(i=1;i<=n;i++)
{
fact=1;
for(j=1;j<=i;j++)
{
fact*=j;
}
term=pow(x,i)/fact*sign;
cout<<term<<"   ";
sum+=term;
sign*=-1;
}
return(sum);
}
int main()
{
series s1;
double x,n;
cout<<"enter limit & value of variable:";
cin>>n>>x;
float result=s1.generate(x,n);
cout<<"\nsum of above series:"<<result<<endl;
return 0;
}

The output of following code is as follows:
