Question

Hi this is C++, I'm really struggle with it please help me....

************************

Here is the original high score program,:

Write a program that records high-score data for a fictitious game. The program will ask the user to enter five names, and five scores. It will store the data in memory, and print it back out sorted by score.

The output from your program should look exactly like this:

Enter the name for score #1: Suzy
Enter the score for score #1: 600
Enter the name for score #2: Kim
Enter the score for score #2: 9900
Enter the name for score #3: Bob
Enter the score for score #3: 1012
Enter the name for score #4: Armando
Enter the score for score #4: 8000
Enter the name for score #5: Tim
Enter the score for score #5: 514

Top Scorers:
Kim: 9900
Armando: 8000
Bob: 1012
Suzy: 600
Tim: 514

Additional Requirements:

The data must be stored in two arrays: an array of strings named names, and an array of ints named scores. These arrays must be declared in the main function.

All of the user input should be done in a function named initializeArrays(). It should have the following signature:

void initializeArrays(string names[], int scores[], int size)

You must also write two more functions: one to sort both arrays, and one to display the final list of names and scores. They should have the following signatures.

void sortData(string names[], int scores[], int size)
void displayData(const string names[], const int scores[], int size)

The main function should be very short. It should just declare the arrays and then invoke these three functions.

****************************

Another additional requirements:

This high scores program should start out by asking the user how many scores will be entered. It should allocate appropriate arrays.

******************************

Here is the latest assignment requirement.

Rewrite your most recent high scores program so that each name/score pair is stored in a struct named highscore. Except as noted below, this new program will continue to meet all of the requirements of the original high scores program. Your new program should meet the following requirements:

The highscore struct should have two fields:

an int named score

and a char array named name. The char array should have 24 elements, making the maximum length of the name 23. (If you prefer to use a char pointer and a dynamically allocated array, that is fine as well. However, this may result in a number of complications, so be prepared for the challenge.)

The data should be stored in a single array, a dynamically allocated array of highscore structs.

Your program should use three functions that accept the array of highscore structs:

void initializeData(highscore scores[], int size)
void sortData(highscore scores[], int size)
void displayData(const highscore scores[], int size)

You may use any sort algorithm, but I would recommend using the selection sort from lesson 9.6. Don't use C++'s sort() function, but you can use the swap() function.

Note that when you swap your array elements, you can swap the entire struct. You don't need to swap the name and the score separately.

You may assume that the user enters names that are 23 characters or less. Getting this to work correctly if the user enters names that are too long -- that is, making it so that you put the first 23 characters in the name variable and ignore the remaining characters on the line -- is complicated. You can do this as an extra challenge if you want, but it's not required.
