C++ pass array as pointer and sort in bubble

#include <iostream>
#include <uuid/uuid.h>
#include <vector>
#include <DynamicArray.h>
#include <MathHelper.h>
#include <random>

void arrayOrder6(int *arrP,int len);
void initArray7();

int main()
{
    initArray7();
    return 0;
}

void initArray7()
{ 
    int arr[100];
    for(int i=0;i<100;i++)
    {
        arr[i]=rand()%100000;        
    }

    printf("Before sort:\n");
    for(int i=0;i<100;i++)
    { 
        printf("%d\t",arr[i]);
    }

    arrayOrder6(arr,100);
    printf("\n\nAfter sort:\n");
    for(int i=0;i<100;i++)
    { 
        printf("%d\t",arr[i]);
    }
    printf("\n\n");
}

void arrayOrder6(int *arrP,int len)
{
    for(int i=0;i<len;i++)
    {
        for(int j=i+1;j<len;j++)
        {
            if(*(arrP+i)>*(arrP+j))
            {
                int temp=*(arrP+i);
                *(arrP+i)=*(arrP+j);
                *(arrP+j)=temp;
            }
        }
    }
}

1.The above is the completed source code 

2.Compile via the below command via g++

g++ -g -std=c++2a -I.  DynamicArray.cpp MathHelper.cpp h1.cpp -o h1 -luuid

The effect of compiled will be illustrated as below snapshot

 3.Run the compiled output ./h1

4.The finally result as below

Pay more attention when pass array as pointer

arrayOrder6(arr,100);
