Thread: One error with pointers

I need help with pointers, I am getting the following error:

error C2664: 'showArray' : cannot convert parameter 1 from 'int *' to 'int *[]' for both of these functions:

Code:

void sort(int *[], int);
void showArray(int *[], int);

I have run out of ideas, please help!

Code:

#include <iostream>
#include <iomanip>
using namespace std;

//Function prototypes
int getnumtestscores();
void gettestscores(int[], int);
void sort(int *[], int);
void showArray(int *[], int);
double average(int [], int);


int main()
{
	int numts = getnumtestscores();

	int *testscores;
		
	testscores = new int[numts];		//To dynamically allocate an array

	gettestscores(testscores, numts);

    cout << "The average of all " << numts << " test scores is: " 
         << fixed << showpoint << setprecision(2)
         << average(testscores, numts);

	cout << "The testscores are: " << showArray (testscores, numts);
	cout << "The numbers sorted are: " << sort (testscores, numts);

    // Free dynamically allocated array in memory
    delete [] testscores;
    // Make scores point to null
    testscores = 0;

	return 0;
}

int getnumtestscores()
{
    int num;

    cout << "\n How many test scores do you want to enter : ";
    for(;;) // loop forever  ... until return
    { 
        cin >> num;
     
        return num;
    }  
}

void gettestscores(int testscores[], int numts)
{
	cout << "What are the testscores for the students?\n";

	for (int count = 0; count < numts; count++)
	{
		cout << "Testscore " << setw(2) << (count+1) << ":";
		cin >> testscores[count];

		if (testscores < 0)		//Input validation
		{
			cout << "An invalid score was entered, please enter a score more than 0\n";
		}
	}
}

void sort(int *array[], int numts)
{
	int lowIndex, *lowest;

	for (int count = 0; count < (numts-1); count++)
	{
		lowIndex = count;
		lowest = array[count];
		for (int index = count + 1; index < numts; index++)
		{
			if (*(array[index]) < *lowest)
			{
				lowest = array[index];
				lowIndex = index;
			}
		}
		array[lowIndex] = array[count];
		array[count] = lowest;
	}
}

void showArray(int *array[], int numts)
{
	for (int count = 0; count < numts; count++)
		cout << *(array[count]) <<" ";
	cout << endl;
}

double average(int *array[], int numts)
{
	int total = 0, *testscores;			//Accumulator
	double average;						//To average testscores

	for (int count = 0; count < numts; count++)
	
		total +=testscores[count];

	  return total/numts;
}

Code:

	for (int count = 0; count < numts; count++)
	{
		cout << "Testscore " << setw(2) << (count+1) << ":";
		cin >> testscores[count];

		if (testscores < 0)		//Input validation
		{
			cout << "An invalid score was entered, please enter a score more than 0\n";
		}
	}

Your input validation needs some help. It doesn't help to validate the input after you place the input into the array.

Thanks bithub, I would work on my input validation as well.
