Array help

[aaronf89]

I'm working on an array program, it's doing what I need it to so far but, I'm having trouble getting it to do two things. I'm not sure how to get it to output Your array is: (numbers entered by user) and how to get it to output the minimum and maximum numbers. This is being done solely using functions/modules per instructor direction. The following is what I have so far. Any help would be greatly appreciated.

#include <iostream>
#include <string>

using namespace std;

void userEntryArray(int numArray[10]);
void printArray(int[10]);
bool checkUserEntry(int entry); 

int main()
{
	//Declaration Block
	int numArray[10];
	int userEntry;

	userEntryArray(numArray);

	printArray(numArray);

	system("pause");

	return 0;
}

void printArray(int numArray[10])
{
	for (int i = 0; i < 10; i++)
	{
		cout << numArray[i] << " ";
	}
	cout << endl;
}

void userEntryArray(int numArray[10])
{
	int userEntry = 0;
	
	for (int i = 0; i < 10; i++)
	{
		cout << "Enter a number: ";
		cin >> userEntry;

		numArray[i] = userEntry; 
	}
	cout << endl;
}

bool checkUserEntry(int entry)
{
	if (entry > -100 && entry < 1000)
	{
		return true;
	}
	else
	{
		return false;
	}
}

Your printArray function does that. The only thing it is missing is:

  //  After line 26
  cout << "Your array is: ";

and how to get it to output the minimum and maximum numbers.

I would suggest you write two more functions:
find_lowest_number()
find_largest_number()

BTW, you never call checkUserEntry()

[aaronf89]

I'm not sure on writing the function for finding the largest and smallest, any suggestions? Also not sure where to call checkUserEntry

[aaronf89]

I did get it printing out, thank you on that by the way.

changing the return type of checkUserEntry() to void:

#include <iostream>
#include <algorithm>

constexpr auto SIZE = 4;
const int lowNum = -100;
const int hiNum = 1000;

void userEntryArray(int numArray[SIZE]);
void printArray(int[SIZE]);
void checkUserEntry(int& entry);//pass by reference

int main()
{
	//Declaration Block
	int numArray[SIZE];
	//int userEntry;

	userEntryArray(numArray);

	printArray(numArray);

	//system("pause");
	//for (auto i = 0; i < SIZE; ++i)std::cout << numArray[i] << " "; std::cout << "\n";

	auto mn = std::minmax_element(numArray, numArray + SIZE);
        //http://en.cppreference.com/w/cpp/algorithm/minmax_element

	std::cout << "Minimum array element: " << *(mn.first) << "\n";
	std::cout << "Maximum array element: " << *(mn.second) << "\n";

	return 0;
}
void printArray(int numArray[SIZE])
{
	for (int i = 0; i < SIZE; i++)
	{
		std::cout << numArray[i] << " ";
	}
	std::cout << "\n";
}
void userEntryArray(int numArray[SIZE])
{
	for (int i = 0; i < SIZE; i++)
	{
        std::cout << "Enter array element# " << i + 1 << ": \n";
		checkUserEntry(numArray[i]);
	}
}
void checkUserEntry(int& entry)
{
	bool match{false};
	while (!match)
    {
        std::cin >> entry;
        if (entry < lowNum || entry > hiNum)
        {
            std::cout << "Incorrect entry, try again \n";
        }
        else
        {
            match = true;
        }
    }
}
