What do lines 10-16 output? ```cpp#include using namespace std;typedef char box[4][8];int main(){ box b[3][2]; cout << sizeof(b) << endl; cout << sizeof(b+0) << endl; cout << sizeof(*(b+0)) << endl; cout << "b is: " << b << endl; cout << "b+1 is: " << b+1 << endl; cout << "&b is: " << &b << endl; cout << "&b+1 is: " << &b+1 << endl; return 0;}```### ExplanationThis C++ program demonstrates the use of multidimensional arrays and pointers. Here's a breakdown of its components:1. **Typedef Definition**: - `typedef char box[4][8];` creates an alias `box` for a 2D array of `char` with dimensions 4x8.2. **Main Function**: - `box b[3][2];` declares a 3x2 array of type `box`. This results in an actual array of dimensions 3x2x4x8.3. **Size Calculations**: - `sizeof(b)`: Calculates the total size of the array `b`. - `sizeof(b+0)`: Calculates the size of a pointer to the beginning of the array. - `sizeof(*(b+0))`: Calculates the size of the first "box" (4x8 array of chars).4. **Pointer Arithmetic**: - `b` and `b+1`: Shows the base address of `b` and the address after the first "row" (box) increment. - `&b` and `&b+1`: Shows the address of the entire 3x2 array `b` and one increment beyond it.This program helps in understanding how arrays and pointers relate to memory addresses and sizes in C++.

Computer Fundamentals

The computer is termed computation. For calculating or computing something the device that has been used is known as the computer. Or we can say that for performing a fast arithmetic operation the device that has been used is a computer. Storing, processing, and retrieving are the main features of a computer. 

Question

What do lines 10-16 output?

```cpp
#include <iostream>

using namespace std;

typedef char box[4][8];

int main()
{
box b[3][2];
cout << sizeof(b) << endl;
cout << sizeof(b+0) << endl;
cout << sizeof(*(b+0)) << endl;
cout << "b is: " << b << endl;
cout << "b+1 is: " << b+1 << endl;
cout << "&b is: " << &b << endl;
cout << "&b+1 is: " << &b+1 << endl;

return 0;
}
```

### Explanation

This C++ program demonstrates the use of multidimensional arrays and pointers. Here's a breakdown of its components:

1. **Typedef Definition**:
- `typedef char box[4][8];` creates an alias `box` for a 2D array of `char` with dimensions 4x8.

2. **Main Function**:
- `box b[3][2];` declares a 3x2 array of type `box`. This results in an actual array of dimensions 3x2x4x8.

3. **Size Calculations**:
- `sizeof(b)`: Calculates the total size of the array `b`.
- `sizeof(b+0)`: Calculates the size of a pointer to the beginning of the array.
- `sizeof(*(b+0))`: Calculates the size of the first "box" (4x8 array of chars).

4. **Pointer Arithmetic**:
- `b` and `b+1`: Shows the base address of `b` and the address after the first "row" (box) increment.
- `&b` and `&b+1`: Shows the address of the entire 3x2 array `b` and one increment beyond it.

This program helps in understanding how arrays and pointers relate to memory addresses and sizes in C++.
