Description: This program calculates sum of series of type 1+1+2+1+2+3+1+2+3+4+ …(1+2+3+…+n).

Code:

//Compiling Tool: Code::Block IDE with MinGW

//Program calculates sum of series of type 1+1+2+1+2+3+1+2+3+4+…………..1+2+3+………+n.

#include<conio.h> //for getch()

 

using namespace std;

 

int main()

{

 

    int i,j,n,sum=0;

    cout<<"Series Type:1+1+2+1+2+3+1+2+3+4+...(1+2+3+………+n)"<<endl;

    cin>> n;

 

    for(i=1; i<=n; i++)

    {

        for(j=1; j<=i; j++)

        {

            sum+=j;

            if(j==n)

            {

                cout<<j;

            }
