I am learning C++ and i am really stuck on a question. Can someone please help because its driving me crazy, please help.

The question is:

To find value of the sum S for which formula composed. Summation (The act or process of adding) to continue until next composed |a[i]|> E.Ispolzovat a heading file and indexes on function for calculation composed under the formula and indexes on a variable.

What the hell is it about? I need to create a formula to complete the question. Can someone please help

Janet

Janet,

I'm having trouble parsing that question -- is that exactly how it was stated?

I'm confused from reading your question also, but. . . I think you are referring to the mathematical term "Summation" (which uses the Greek letter Sigma). Summation uses recursion which is illustrated in Bruce Eckel's Thinking in C++ tutorial as:
void removeHat(char cat) {
  for(char c = 'A'; c < cat; c++)
    cout << " ";
  if(cat <= 'Z') {
    cout << "cat " << cat << endl;
    removeHat(cat + 1); // Recursive call
  } else
    cout << "VOOM!!!" << endl;
}
