Dear all, I need the code for counting sort algorithm but I try this code but is not working

```
#include <iostream>
#include <conio.h>
#include <time.h>
#include <stdlib.h> //srand and rand functions
using namespace std;
void add_random_numbers(long arr[], long b);
void countingSort( long left, long right, long vector[], int k, long length);
long const MADH_MAX_VEKTORIT = 110000;
int main()
{
long random_vector[MADH_MAX_VEKTORIT];
long vector[] = { 1000, 10000, 15000, 25000, 30000, 45000, 50000, 60000, 75000, 90000, 100000 };
long num_elem;
clock_t tn, tp;
srand(time(NULL));
cout << "AlgorithmttNumbers_of_emelmentstttTime(s)n";
cout << "--------tt-------------------tt-------n";
for (long i = 0; i < 11; i++)
{
num_elem = vector[i];
add_random_numbers(random_vector, num_elem);
tn = clock();
countingSort(random_vector, 0, num_elem);
tp = clock();
cout << "countingSort ttt" << num_elem << "ttt" << (tp - tn) / (double)CLOCKS_PER_SEC << endl;
}
getchar();
return 0;
}
void add_random_numbers(long arr[], long b)
{
for (long i = 0; i < b; i++)
arr[i] = rand();
}
void countingSort(long vector[], int k, long length)
{
int c[] = new int[k];
for (int i = 0; i < vector.length; i++)
c[vector[i]]++;
for (int i = 1; i < k; i++)
c[i] += c[i - 1];
int b[] = new int[vector.length];
for (int i = vector.length - 1; i >= 0; i--)
b[--c[vector[i]]] = vector[i];
return b;
}
```
