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:
