Merge Sort in C++

MergeSort.cpp

#include <iostream>

void printArray(int *array, int n)
{
    for (int i = 0; i < n; ++i)
        std::cout << array[i] << std::endl;
}

void merge(int *array, int low, int mid, int high)
{
    int temp[high + 1];
    int i = low;
    int j = mid + 1;
    int k = 0;

    while (i <= mid && j <= high)
    {
        if (array[i] <= array[j])
            temp[k++] = array[i++];
        else
            temp[k++] = array[j++];
    }
    while (i <= mid)
        temp[k++] = array[i++];
    while (j <= high)
        temp[k++] = array[j++];
    k--;
    while (k >= 0)
    {
        array[k + low] = temp[k];
        k--;
    }
}

    int mid;

    if (low < high)
    {
        mid = (low + high) / 2;
        mergeSort(array, low, mid);
        mergeSort(array, mid + 1, high);

    int n = sizeof(array)/sizeof(array[0]);

    std::cout << "Before Merge Sort :" << std::endl;
    printArray(array, n);

tried to run your code it can't run. new to cpp though

probeer dit :)

In cpp you cannot use temp[high+1], you have to create dynamic array like int *temp=new int[high+1] and at the end of merge function delete this temp by using this statement delete[]temp.
