Quick Sort in C++

QuickSort.cpp

#include <iostream>

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

void quickSort(int *array, int low, int high)
{
    int i = low;
    int j = high;
    int pivot = array[(i + j) / 2];
    int temp;

    while (i <= j)
    {
        while (array[i] < pivot)
            i++;
        while (array[j] > pivot)
            j--;
        if (i <= j)
        {
            temp = array[i];
            array[i] = array[j];
            array[j] = temp;
            i++;
            j--;
        }
    }
    if (j > low)
        quickSort(array, low, j);
    if (i < high)
        quickSort(array, i, high);
}

int main()
{
    int array[] = {95, 45, 48, 98, 1, 485, 65, 478, 1, 2325};
    int n = sizeof(array)/sizeof(array[0]);

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

    quickSort(array, 0, n);

    std::cout << "After Quick Sort :" << std::endl;
    printArray(array, n);
    return (0);
}

how can i make it full quick sort ?

thank you very much

Thanks

Nice code, bro 👍

Thanks a lot....

Thx, u are the best

int array[] = {0, 0};

👍👍

quickSort(array, 0, n-1); high must be n-1.

quickSort(array, 0, n-1); high must be n-1.

👍

Там n+1 должно быть в последнем выводе

#include

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

void quickSort(int *array, int low, int high)
{
int i = low;
int j = high;
int pivot = array[(i + j) / 2];
int temp;

while (i <= j)
{
    while (array[i] < pivot)
        i++;
    while (array[j] > pivot)
        j--;
    if (i <= j)
    {
        temp = array[i];
        array[i] = array[j];
        array[j] = temp;
        i++;
        j--;
    }
}
if (j > low)
    quickSort(array, low, j);
if (i < high)
    quickSort(array, i, high);

}

int main()
{
int array[] = {95, 45, 48, 98, 1, 485, 65, 478, 1, 2325, 37};
int n = sizeof(array)/sizeof(array[0]);

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

quickSort(array, 0, n);

std::cout << "After Quick Sort :" << std::endl;
printArray(array, n+1);
return (0);

}
