Question

using my code in c++ , I need help adding to it. I need to take my 2D array and put it in to 1D array format 

```cpp using namespace std; int main() { int rows, columns; //declare int variables int count = 0; //starting my count from zero, this will create the numbers in my grid cout << "Please enter the number of rows: "; //prompt cin >> rows; //get user input cout << "Please enter the number of columns: "; //prompt cin >> columns; //get user input cout << "\nI have " << rows << " rows and " << columns << " columns. I need to fill up " << rows * columns << " spaces." << endl; //print to user the numbers they entered for rows and columns and the grid number multiplied cout << "\nThe " << rows << " x " << columns << " array:" << endl; //print to user for (int i = 0; i < rows; i++) //row by row { for (int j = 0; j < columns; j++) //j for column by column { cout << count << "|"; //print this symbol to separate the numbers count++; //increase the counter by one } cout << endl; //each time a row is done, end the line to start the next row } return 0; //end program } ``` This code is a simple C++ program that generates a grid of numbers based on user input for the number of rows and columns. ### Explanation: - **Variable Declaration**: - `int rows, columns`: Declare integer variables for storing user input. - `int count = 0`: Initialize a counter to zero for numbering grid elements. - **User Input**: - Use `cin` to get the number of rows and columns from user input. - **Output**: - Print statements inform the user of their input and the size of the grid. - **Grid Generation**: - Nested `for` loops iterate over rows and columns. - The `count` variable is printed and then incremented, creating a grid pattern. - Each row is ended with `endl` to move to a new line. This program visually demonstrates how a simple nested loop structure can be used to populate a two-dimensional grid with sequential numbers.

**Sample Output #1:** - Please enter the number of rows: **4** - Please enter the number of columns: **4** I have 4 rows and 4 columns. I need to fill-up 16 spaces. **The 4x4 array:** ``` 1|2|3|4| 5|6|7|8| 9|10|11|12| 13|14|15|16| ``` The 4x4 2-D array flattened into a 16 cell 1-D array: ``` 1|2|3|4|5|6|7|8|9|10|11|12|13|14|15|16| ``` --- **Sample Output #2:** - Please enter the number of rows: **3** - Please enter the number of columns: **2** I have 3 rows and 2 columns. I need to fill-up 6 spaces. **The 3x2 array:** ``` 1|2| 3|4| 5|6| ``` The 3x2 2-D array flattened into a 6 cell 1-D array: ``` 1|2|3|4|5|6| ```
