Creating New Numbers in a Random Array

[iNhpfSEw]

So I posted this earlier to receive OOP help with my code, but I dropped the Object Oriented programming aspect. My goal is to create an array of ten random integers and sort them in order. Problem is, we need to do this in 3 different languages. I only know Java and BASIC. C++ is new to me. I have everything working on my code EXCEPT that I don't get new numbers when I run the code:

#include <iostream>
using namespace std;

    int sort ();
    int arrayValue;
    int array [10];
    int temp;
     
/**
* Compares the value of two elements in myArray[]
* and sorts them in order by value
*/
int sort () 
{
    for(int y = 0; y < 10; y ++)
    {
        for(int j = 0; j < 10; j ++)
        {
            if (array[j+1] > array[j])      
            { 
                temp       = array[j];            
                array[j]   = array[j+1];
                array[j+1] = temp;
            }            
        }
    }

    for(int t = 0; t < 10; t ++)
    {
        cout << array[t];
        cout << " ";
    }
    while(1);
}
    
/**
* The main () method starts everything
*/
int main ()
{
    for(int x = 0; x < 10; x ++)
    {
        array[x]  = rand() % 100;
        
        cout << array[x];
        cout << " ";
    }
        
    cout << "  ";
    sort ();  // Runs the sort () method
}

Any suggestions on how to create new numbers when I run this?
P.S Remember I am very new to C++

Seed the random number generator, once, right at the beginning of main.

std::srand( std::time(0) ) ; // #include <ctime>

Can you explain it in terms of my code? I'm not asking for the answer, but I don't know what to put where.

Like this..

// Random array numbers.cpp : main project file.
#include <iostream>
#include <ctime>

using namespace std;

int sort ();
int arrayValue;
int array [10];
int temp;
     
/**
* Compares the value of two elements in myArray[]
* and sorts them in order by value
*/

    
/**
* The main () method starts everything
*/
int main ()
{
    srand((unsigned) time(0)); // To use the random function and get
	                           // different numbers, using time

	cout << endl << endl << "Unsorted numbers in array" << endl;
	for(int x = 0; x < 10; x ++)
    {
        array[x]  = rand() % 100;
        
        cout << array[x];
        cout << " ";
    }
        
    cout << "  ";
    sort ();  // Runs the sort () method
}

int sort () 
{
    
	for(int y = 0; y < 10; y ++)
    {
        for(int j = 0; j < 9; j ++) // Needs to be 1 less than array size
			                        // else array out of bounds with j+1
        {
            if (array[j+1] > array[j])      
            { 
                temp       = array[j];            
                array[j]   = array[j+1];
                array[j+1] = temp;
            }            
        }
    }

	cout << endl << endl << "Sorted numbers in the array" << endl;
    for(int t = 0; t < 10; t ++)
    {
        cout << array[t];
        cout << " ";
    }
	cout << endl << endl;
	return 0;
}
