Write a program that allocates an array large enough to hold a ... (continues in description)

Question

(continued from title) ...user-defined number of test scores. Once all the scores are entered, the array should be passed to a function that sorts them in ascending order. Another function should be called that calculates the average score. The program should drop the lowest grade before determining the average. The program should display the sorted list of scores and averages with appropriate headings to a file. Input Validation: Do not accept negative numbers for test scores.

Answer 1

I can give you some hints, but not the entire solution. There are 2 methods to allocate the array that is large enough to store scores:

Use vector:

#include <vector>

// Declare dynamic score array and read in scores:

vector<int> myscores(20); // 20 is the initial size your dynamic array

// read each score by using cin:

// you need a while-loop to read in each score

cin >> myscores[i];

Ask the user for the max number of score and dynamically allocate enough storage:

int *mycores = new int [number_of_scores];

// Use a while-loop to read in each scores similar to above

The sorting function prototype should be:

void sort_scores(int *myscores, int score_count)

// myscores: the input score array

// score_count: the number of scores in myscores array

// Your text book should have an example of sorting an integer array

The average function prototype should be:

float average((int *myscores, int score_count)

// You should be able to figure out the rest
