Hello friends, I'm working on a program that takes a number input from the user and recursively sums the number 'n' to one. For example, inputting a 5 would sum 1/5 + 1/4 + 1/3+ 1/2 + 1/1. I have sucessfully gotten the fraction sequence to display but I am having trouble with the sum.
Here is my client program

#include "Fraction.cpp"
#include<iostream>
using namespace std;
Fraction SumOfSeries(int n);//adds fractions from num to 1
int main()
{
    int num;
    cout<<"Enter a number: ";
    cin>>num;
    cout<<"Sum of Series-> ";
    SumOfSeries(num);
    char wait;
    cout<<"\nEnter any key to end ";
    cin>>wait;
    return 0;
} 
Fraction SumOfSeries(int n)
{
    Fraction base(1,1);
    Fraction temp(1,n);
    if(n==1)
            {
                       base.Display();
                       return base;
            }
    else
        {
            for(int i=1; i<=n; i++)
            {
            base=base+temp;
            temp.Display();
            if(i!=n)
            cout<<" + ";
            return temp+SumOfSeries(n-1); 
            } 
        }      

}

Here is my fraction class (you probably don't need to spend too much time looking at this.

#include <iostream>
using namespace std;

{public:
        Fraction();
        Fraction(int n, int d);

        int GetNum();
        int GetDen();
        double Convert();
        Fraction operator+(Fraction f);
        Fraction operator*(Fraction f);
        Fraction operator-(Fraction f);
        Fraction operator/(Fraction f);
        bool operator>(Fraction f);
        bool operator<(Fraction f);
        bool operator==(Fraction f);
        void Reduce();

Thanks for any help.

Firstly you are returning a Fraction type but not stroring or displaying it.

Fraction frac=SumOfSeries(num);
frac.display;

Secondly in Function SumOfSeries Why are you introducing a for loop?

#include "Fraction.cpp"
#include<iostream>
using namespace std;

Fraction SumOfSeries(int n);//adds fractions from num to 1
int main()
{
    int num;
    cout<<"Enter a number: ";
    cin>>num;
    cout<<"Sum of Series-> ";
    Fraction frac=SumOfSeries(num);
    frac.Display();	
    char wait;
    cout<<"\nEnter any key to end ";
    cin>>wait;
    return 0;
} 
Fraction SumOfSeries(int n)
{
    Fraction base(1,1);
    Fraction temp(1,n);
    if(n==1)
            {
                       return base;
            }
    else
        {
            return temp+SumOfSeries(n-1); 
        }      

}

This code returns the correct output.
All you need to do is write a print function which writes down... all the numbers such as

writenumbers(int n)
{
for(int i=1; i<=n; i++)
            {
            Fraction temp(1,n);
            temp.Display();
            if(i!=n)
            cout<<" + "; 
            }
}

Thanks for the reply but I need to use recursion (i.e. the function has to call itself) to solve this problem.

Sorry, I followed your first piece of advice and got the sum to display. Thanks alot for the help.
