A function which will display the contents of an array being sorted c++ using insertion sort

Question

I have error, which is highlighted "cout << array[i] << endl;" in this section. The line is under array[i]. The error is "argument list for class template "std::array" is missing ". i need a function to display the contents of an array, using an insertion sort. If this code is incorrect, does anyone know the code to output the contents of the array, using linear search.

#include <iostream>
#include <string>
#include <sstream>
using namespace std;



int main()
{
    int numbers[SIZE] = { 6,3,1,9,4,12,17,2 };
    for (int i = 0; i < 8; i++)
    {
        cout << array[i] << endl;
    }

    system("pause");
}

const int SIZE = 8;
void insertionSort(int numbers[], int arraySize)
{
    int i, j, insert;

    for (i = 1; i < arraySize; i++)
    {
        insert = numbers[i];
        j = i;
        while ((j > 0) && (numbers[j - 1] > insert))
        {
            numbers[j] = numbers[j - 1];
            j = j - 1;
        }
        numbers[j] = insert;

    }
}

Answer 1

You didn't call your function insertionSort(int numbers[], int arraySize) in main(). Therefore nothing will happen to the original array.

Note that you need a return 0; statement inside int main(). And that you need to use numbers[i] instead of array[i]. And you need to set your insertionSort() to return "something" or to pass your numbers[] as a reference. Also not to forget about the function prototype before main().

This should work:

const int SIZE = 8;
void insertionSort(int [], int);

int main()
{
    int numbers[SIZE] = { 6,3,1,9,4,12,17,2 };
    insertionSort(numbers, SIZE);
    for (int i = 0; i < 8; i++)
        cout << numbers[i] << endl;

    system("pause");
    return 0;
}

void insertionSort(int MyArray[], int size)
{
    int i, j, insert;

    for (i = 1; i < size; i++){
        insert = MyArray[i];
        j = i;
        while ((j > 0) && (MyArray[j - 1] > insert)){
            MyArray[j] = MyArray[j - 1];
            j = j - 1;}
        MyArray[j] = insert;}
}
