How to make overlapped series (C++)

Overlapped series

This example shows how to execute two different series in a single for loop at a time. First one satring from 1 which increaments by 1, and the second one also strating from 1 and it increaments by 2.

overlappedSeries() calculates the overlapped series and it takes 1 parameter:

num is the number of times the for loop will execute.

Code

#include "stdafx.h"

#include "iostream"

#include "conio.h"

#include "iomanip"

using namespace std;

void overlappedSeries(int num)

{

 for(int i =1,j=1;i<=num;i=i+1,j=j+2)

 {

  cout<<i<<" "<<j<<" ";

 }

 cout<<endl;

}

int main()

{

       overlappedSeries(5);cout<<endl;

       overlappedSeries(6);cout<<endl;

       overlappedSeries(7);cout<<endl;

       overlappedSeries(8);cout<<endl;

       overlappedSeries(9);cout<<endl;

       _getche();

       return 0;

}

Output

1 1 2 3 3 5 4 7 5 9

1 1 2 3 3 5 4 7 5 9 6 11

1 1 2 3 3 5 4 7 5 9 6 11 7 13

1 1 2 3 3 5 4 7 5 9 6 11 7 13 8 15

1 1 2 3 3 5 4 7 5 9 6 11 7 13 8 15 9 17
