Question
I need help with my code. This is what my I am supposed to do: A sequence of integers such as 1, 3, 5, 7, ... can be represented by a function that takes a nonnegative integer as parameter and returns the corresponding term of the sequence. For example, the sequence of odd numbers just cited can be represented by the function
int odd(int k) {return 2 * k + 1;}
Write an abstract class AbstractSeq that has a pure virtual member function
as a stand-in for an actual sequence, and two member functions
that are passed two integer parameters k and m, where k < m. The function printSeq will print all the terms fun(k) through fun(m) of the sequence, and likewise, the function sumSeq will return the sum of those terms. Demonstrate your AbstractSeq class by creat- ing subclasses that you use to sum the terms of at least two different sequences. Determine what kind of output best shows off the operation of these classes, and write a program that produces that kind of output.
And here is my code:
#include <iostream>
using namespace std;
//Prototypes
int oddSeq();
int doubleSeq();
int sumSeq();
void printSeq();
//Classes
class AbstractSeq
{
public: virtual int fun(int k) = 0;
};
int main()
{
//Variables
int k;
int m;
int rSeq;
//Input
cout << "How long do you want the sequence to be? ";
cin >> rSeq;
//Output
printSeq();
return 0;
}
//Odd numbers sequence.
int oddSeq(int k)
{
return 2 * k + 1;;
}
//Double the numbers sequence.
int doubleSeq()
{
return;
}
//Sums of all the numbers.
int sumSeq()
{
int totalSum;
return totalSum;
}
//Output the sequence.
void printSeq()
{
}
Explanation / Answer
#include <iostream>
using namespace std;
//Prototypes
int oddSeq();
int doubleSeq();
int sumSeq();
void printSeq();
//Classes
class AbstractSeq
{
public: virtual int fun(int k) = 0;
};
//Odd numbers sequence.
int oddSeq(int k)
{
return 2 * k + 1;;
}
//Sums of all the numbers.
int sumSeq(int k,int m)
{
int totalSum=0;
int i;
for(i=k;i<=m;i++)
{
totalSum+=oddSeq(i);
}
return totalSum;
}
//Output the sequence.
void printSeq(int k,int m)
{
int i;
for(i=k;i<=m;i++)
{
cout << oddSeq(i)<<endl;
}
}
int main()
{
//Variables
int k;
int m;
int rSeq;
//Input
cout << "How long do you want the sequence to be? ";
cin >> rSeq;
//Output
cout <<" "<<endl;
printSeq(1,rSeq);
cout << "The sum is "<<sumSeq(1,rSeq)<<endl;
return 0;
}
