12) 8 pts. Find the errors in the following code fragment and correct them. #i nclude <iostream> using namespace std; double fudge (double s) f return s 2.3; int mainO cout >> "Your original estimate" double estimate; cin >> estimate; cout << endl; for (int 1 = 0;1c3;i++); cout << "EStimate' < fudge(estimate) <<endl Hint: There are 4 syntax errors. There is one error that is syntactically correct but causes the output to not be what you would expect. Once...
31. The following code segment is syntactically correct: int number{20}; cout << number << setbase(16) << " " << number << setbase(10) << " " << number << showpos << " " << number << endl; T__ F__ 32. The following statement wants to determine if ‘count’ is outside the range of 0 through 100: if (count < 0 && count > 100) T__ F__ 33. There is...
