i got the solution, i think its correct double sum, i; for (i = 1, sum = 0; i <= 100000000; i++); sum = sum +1/i; cout << "Sum is " << sum << endl;

logic should be like this ...correct me if i m wrong double sum = 0.0; double m = 1; while(true) { sum += 1/m; m++; if (m >10) break; } //Print sum; And btw i don't know C++

your solution seems to be correct. I have one suggestion"i" can be declared as integer, but will not hold up to "100000000" number, it should be declared as long or long long. double is for floating point numberI am guessing that u got negative answer at first because you forgot to initialize the "sum" to zero. is that correct :D

double sum, i; for (i = 1, sum = 0; i <= 100000000; i++); sum = sum + 1/i; cout << "Sum is " << sum << endl; remove the semicolon at the end of the second line or else write it as for (i = 1, sum = 0; i <= 10; sum+=1/i, i++);
