Which component of a dialog box provides a quick method of increasing or decreasing a setting?

Frequency analysis refers to:

a. Analyzing the rate of occurrence of characters in ciphertext b. Eavesdropping on spread-spectrum radio frequency transmission in order to harvest encryption keys c. Analyzing the rate of occurrence of characters in plaintext d. Analysis of emanations in order to harvest encryption keys

Given the class definition and associated code.

a) Modify the code implementing the operator[] to throw an int exception if the index is out of the declared array range. The exception object is to have the value of the out-of-range index. Be sure you add an exception specification to the operator function. b) Modify the code in main that calls operator[] to catch the exception and terminate the program using exit(1). ``` #include using namespace std; class intVec { public: intVec(); intVec(int n); // other members int& operator[](int index); private: int* v; int size; }; intVec::intVec(int n): v(new int[n]) { for (int i=0; i < n; i++) v[i] =0; } int& intVec::operator[](int index) { return v[index]; } int main() { intVec myVec(10); { //Block enclosing "for" is because VC++ does not //define for loop control variables inside the //"for" loop block as the C++ Standard requires for(int i = 0; i < 10; i++) myVec[i] = (i-5)*(i-5); } { for(int i = 0; i < 10; i++) cout << myVec[i] << " "; cout << endl; } int i = -1; cout << "accessing myVec[" << i << "]" << endl; cout << myVec[i] << endl; return 0; } ```
