Your task is to write a function which returns the sum of following series upto nth term(parameter). Series: 1 + 1/4 + 1/7 + 1/10 + 1/13 + 1/16 +... Rules: You need to round the answer to 2 decimal places and return it as String. If the given value is 0 then it should return 0.00 You will only be given Natural Numbers as arguments. Examples: SeriesSum(1) => 1 = "1.00" SeriesSum(2) => 1 + 1/4 = "1.25" SeriesSum(5) => 1 + 1/4 + 1/7 + 1/10 + 1/13 = "1.57"     My Solution     #include <iostream> #include <iomanip> using namespace std; class ta { float ar[50]; int j,f,k,q; float sum=0.00; public: void taa(int k) { f = k; } void paa() { for(j=0; j<f; j++) { ar[j] = 1.00/(1 + j * 3); } } void baa() { for(q=0; q<f; q++) { sum = sum+ar[q]; } cout <<setprecision(3)<< sum; ...
