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...

True/False 1. The results of code fragment sizeof(int*)==sizeof(int) depends on the compiler and architecture. 2. If c is of type int* and b is of type int, c[b] is equivalent to *c+b. 3. Security software focuses on engineering software so that it continues to function correctly under malicious attack. 4. Ethical hacking is about hacking into systems run by those whose ethics you disagree with. 5. Concurrency occurs when two or more separate execution flows are able to run simultaneously.
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...
