In C++ how do I implenement these functions? ### Memory Management and Array Manipulation in C++: A Practical GuideThis guide provides a detailed explanation of handling arrays and memory manipulation in C++, emphasizing operations with days and months. Below are three fundamental procedures: resizing an array of months, constructing a month, and adding a new month to the array.#### Resizing an Array of Months**Procedure: `resizeYearArray`**1. **Create a Temporary Array**: - Construct a temporary array of type `Month` with a size of `numMonths + 1`.2. **Copy Existing Data**: - Iterate through the existing year array, copying each element into the new temporary array.3. **Delete Original Array**: - Delete the original year array to free up memory. - ```cpp delete[] yearArray; ```4. **Update Pointer**: - Assign the temporary array to the year pointer.5. **Increment Maximum Size**: - Update `maxMonths` since the array size has increased.6. **Return Updated Array**: - Return the updated year array to allow the calling function to access the newly allocated memory address.#### Constructing a Month**Procedure: `construct month`**1. **Create a Temporary Array of Days**: - Use the months enumeration defined in the header file to fill the number of days in a month. - Construct a temporary array of type `Day` to hold these days.2. **Loop Through Days**: - Loop from 0 to the month's number of days.3. **Assign Days**: - Inside the loop, create a temporary day object and set its number value according to the loop index (`index + 1`). - Insert this temporary day object into the temporary day array.4. **Create New Month**: - Utilize the `Month` parameterized constructor. - Pass in: 1. The name from the enumeration. 2. The number of days from the enumeration. 3. The array of days created.5. **Delete Temporary Array**: - Delete the temporary day array. - ```cpp delete[] tempDayArr; ```6. **Return Constructed Month**: - Return the newly created month.#### Adding a Month**Procedure: `addMonth`**1. **Check Array Size**: - Compare `numMonths` with ### Code Snippet Transcription and ExplanationThis snippet of C++ code is used for manipulating arrays of a `Month` structure. It includes the declaration of three functions and an inclusion of a header file. Below is the detailed explanation of the provided code:```cpp#include "helpers.h"Month* resizeYearArray(Month* year, int numMonths, int& maxSize) { Month tempArray[numMonths + 1]; int numMonths;}Month constructMonth(months month, string name) {}Month* addMonth(Month newMonth, Month* year, int& numMonths, int& maxSize);```#### Explanation:1. **Including a Header File**: ```cpp #include "helpers.h" ``` This line includes a custom header file `"helpers.h"`. The functions or definitions declared within `"helpers.h"` are made available for use in this file.2. **Function: `resizeYearArray`**: ```cpp Month* resizeYearArray(Month* year, int numMonths, int& maxSize) { Month tempArray[numMonths + 1]; int numMonths; } ``` - **Parameters**: - `Month* year`: A pointer to an array of `Month` objects. - `int numMonths`: The current number of months in the `year` array. - `int& maxSize`: A reference to an integer representing the maximum size of the array. - **Local Variables**: - `Month tempArray[numMonths + 1]`: A temporary array of `Month` objects, sized to hold one additional element. - `int numMonths;`: Redefinition of `numMonths` as a local variable which is usually seen as an error. It shadows the parameter `numMonths`. **Note**: The function's complete implementation is missing, and it contains a syntax error by re-declaring `numMonths` inside the function body.3. **Function: `constructMonth`**: ```cpp Month constructMonth(months month, string name) { } ``` - **Parameters**: - `months month`: Presumably an enumerated type or a type alias representing a month. - `string name`: A `string` representing the name of the month. - The function's body is empty, indicating that

Below is the complete solution with explanation in detail for the given question about the…

- In resizeYearArray, construct a temporary array of type Month that is size numMonths + 1. Iterate through the year array and copy each element from the year into the temporary array you created. Delete the year array, and set the year array equal to the temporary year that you filled. Increment the maxMonths, which will update in main since we're using pass by reference. Return the year array, so that the calling function has access to the newly allocated memory address. - In construct month, construct a temporary array of type Day- use the months enumeration in the header file to fill the number of days in a month, and to fill the days array. Loop from 0 to the month's number of days. Inside the loop create a temporary day object, and set its number value to be the same as the loop index + 1- this will assign dates to each day. Then, insert the temporary day object into the temporary day array. Outside the for loop, use the Month parameterized constructor to create a new month. You should provide it with the name that was passed in, the number of days from the enumeration, and the array of days you just created. Delete the temporary day array using `delete [] tempDayArr` and return the month that you created using the parameterized constructor. - In addMonth, if numMonths and maxSize are equal, call resizeYearArray, and set year equal to the call so that the new pointer is stored. Insert the month at the end of the array using numMonths, then increment numMonths and return the year pointer (since it possibly changed if resizeYearArray was called).
