To add a pre-increment operator to the Time class, we can define the operator function inside the Time class definition. The function should first increment the minutes by 1 and then check if the minutes have exceeded 59. If so, it should increment the hours by 1 and reset the minutes to 0. Here's an example implementation:
class Time {
public:
Time(int hours, int minutes);
Time& operator++() {
++m_minutes;
if (m_minutes > 59) {
m_minutes = 0;
++m_hours;
if (m_hours > 23) {
m_hours = 0;
}
}
return *this;
}
private:
int m_hours; // 0..23
int m_minutes; // 0..59
};
In the Tester.cpp file, we can use the pre-increment operator on a Time object like this:
int main() {
Time a(3, 57);
cout << ++a; // prints 04:58
return 0;
}
Note that we need to return a reference to the Time object from the operator function, so that we can chain multiple pre-increment operations together (e.g. ++a1, ++a2, ++a3). Also, since the pre-increment operator modifies the Time object itself, we don't need to pass it as a parameter to the operator function.
To add a pre-increment ++ operator to the Time class, you need to define the operator in the Time class and implement it in the time.cpp file. Here's how you can do it:
1. Update the Time class definition in time.h to include the pre-increment operator:
```cpp
class Time {
public:
Time(int hours, int minutes);
Time& operator++(); // Pre-increment operator
private:
int m_hours; // 0..23
int m_minutes; // 0..59
};
```
2. Implement the pre-increment operator in time.cpp:
```cpp
#include "time.h"
using namespace std;
// Implementation of pre-increment operator
Time& Time::operator++() {
m_minutes++;
if (m_minutes >= 60) {
m_minutes = 0;
m_hours++;
if (m_hours >= 24) {
m_hours = 0;
}
}
return *this;
}
```
3. Update the main function in Tester.cpp:
```cpp
#include
#include "time.h"
using namespace std;
int main() {
Time a(3, 57);
++a; // Increment the minutes using pre-increment operator
// Output the updated time, assuming you have a display function
// cout << a;
}
```
Now, when you run the program, the pre-increment operator will add 1 to the minutes and roll over the hours if necessary.

What might you need to do to play AIFF on a windows computer?
Need to do to play AIFF on a windows computer - Your computer has to have corresponding codecs installed on it.
About AIFFShort for “Audio Interchange File Format.” AIFF is a file format designed to store audio data.
It was developed by Apple Computer, but is based on IFF Arts Electronic (File Interchange Format), a container format originally used on the Amiga system.
A standard AIFF file contains 2 channels of uncompressed stereo audio with a 16-bit sample size, recorded at a sampling rate of 44.1 kilohertz.
This is also known as “CD-quality audio,” because CDs use the same audio specifications.
AIFF Audio requires more than 10MB per minute of audio, which means a 4-minute song saved as AIFF will take up more than 40MB of disk space.
It is nearly identical to a .wav file (which uses the same sample size and sampling rate as an AIFF file.

which sorting algorithm has the best asymptotic runtime complexity
The sorting algorithm that has the best asymptotic runtime complexity is called "average case" complexity.
What is the sorting algorithm?There are several sorting algorithms that have O(n log n) average case complexity, including:
Merge Sort: This algorithm divides the input array into two halves, sorts each half and then merges them to get the final sorted array.Heap Sort: This algorithm uses a data structure called a heap to sort the input array.Quick Sort: This is a divide and conquer algorithm that partitions the input array into two smaller arrays, and recursively sorts each partition.Therefore, note that there are sorting algorithms with better best-case complexity but this complexity is not achievable in all cases, such as O(n) sorting algorithms like counting sort, bucket sort and radix sort. They are only applicable when certain constraints are met on the input data.
