Random number array sorting

[Blanchy]

I am having trouble getting these values to return correctly, most times everything but descending order works but if i input a 3 everything messes up, any help would be greatly appreciated.

#include<iostream>
#include<algorithm>
#include<vector>
using namespace std;

int compare (const void * a, const void * b)
{
    return ( *(int*)a - *(int*)b );
}

void myOrder(int numb, int random);
void myOrder(int numb, int random)
{
     int asc, des;
     int list[numb];
     
     qsort(list, numb, sizeof(int), compare);
     cout<<"\n\n\nThe "<<numb<<" numbers in Ascending Order ";
     for(int i = 0; i < numb; i++)
     {
             cout<<list[i]<<" ";
     }
     
     cout<<"\nThe "<<numb<<" numbers in Descending Order "; 
     for(int i = numb; i >= 0; i--)
     {
             cout<<list[i-1]<<" ";
     }
         
}

void mySort(int numb, int random);
void mySort(int numb, int random)
{
    int list[numb];
        
    qsort(list, numb, sizeof(int), compare);
    
    cout<<"\n\n\nThe highest number is "<<list[(numb-1)];
    cout<<"\nThe lowest number is "<<list[0];
  
}

int getNumb();
int getNumb()
{
    bool restart = false;
    int numb;
    do
    {
    cout<<"How many numbers would you like to be generated(2-20)? ";
    cin>>numb;
    if ((numb >= 2 )&&(numb <= 20)) 
       {
    cout<<"\n\nThe "<<numb <<" numbers generated are:\n";
    return numb;   
       }
    else 
         {
         cout<<"Sorry, that is invalid try again.\n"; 
         restart = true;
         }
    }
    while (restart == true);
    
}

int myRandom(int numb);
int myRandom(int numb)
{
         int random[numb];
         for (int i = 0; i < numb ; i++)
         {
             random[i] = rand() % 20 + 2;
             cout<<random[i]<<" ";
         }
         return random[0];
}

int main()
{
    int numb, random;
    srand (time(NULL));
    cout<<"Data Searching and Sorting!!\n\n";
    
    numb = getNumb();
    random = myRandom(numb);
    mySort(numb, random);
    myOrder(numb, random);
    
    
cin.get();
cin.get();
return 0;   
}

In myRandom, random is a local array that ceases existing when the function ends, so all of the assignments you've made to individual elements are lost. (Besides that, C++ requires array sizes to be compile time constants so line 71 is illegal.)

In mySort, list is a local array with uninitialized elements that could be any value at all. (Besides that, C++ requires array sizes to be compile time constants so line 35 is illegal.)

In myOrder, list is a local array with uninitialized elements that could be any value at all. (Besides that, C++ requires array sizes to be compile time constants so line 15 is illegal.)

You may want to disable the extension that allows those illegal lines.

Thanks for the advice, I hate this bloodshed compiler. Any chance you know where the option would be to block those lines?

The bloodshed IDE is no longer developed (and if you downloaded the package from their website it comes with an outdated version of the GCC compiler.) I would suggest getting rid of it at the earliest opportunity. If you want to stick with a similar IDE, the Orwell branch is actively developed. Code::Blocks is another popular choice to use with GCC.

I believe the option you need to disable extensions with GCC is -pedantic.
