Question

Write a C++ program to calculate scientifically the
following summation

using a variable of double type to keep the sum in the
program. The program should also display the final
result. Desk-check the first few steps of your
program while monitoring the relevant variable/s and
condition/s. These first few steps should include at
least the processing of the first 2 terms, i.e.
3/(1×2)+4/(2×3). For the desk-checking, please label
the lines or the statements of your C++ program explicitly.

Explanation / Answer

#include<iostream>
using namespace std;

int main()
{
double sum=0;

for(double i=3.0; i<102.0; i++)
{
sum = sum + (i/((i-2)*(i-1)));
if(i==4)
cout << " Sum is " << sum <<endl; // this equals to 3/1*2 + 4/2*3
}
cout << " Total sum of Series Given by " << sum <<endl;

return 0;
}
