Vector, same value on same row

[markusfurst]

In the output for the sorted integers they know display in one long column. I would like the 1:s on one row the 2:s on one row etc..
For example

1 1 1
2 2
3 
4 4 

How do I do that?

#include <iostream>
#include <vector>
#include <iomanip> 
#include <ctime>
#include <random>
#include <algorithm>

using namespace std;

int main()
{
    vector<int> randomIntegers;
    int num;
    
    default_random_engine generator(static_cast<int>(time(0)));
    uniform_int_distribution<int> random(1, 100);
    
    
    vector<int> randomIntegers2;
    randomIntegers2 = randomIntegers;
    
    
    cout << " How many integers do you want to randomize: " ;
    cin >> num;
    
    
    for(int i=0; i < num; i++)
        randomIntegers.push_back(random(generator));
  
    int cnt = 1;
    for(auto e : randomIntegers)
    {
        cout << setw(5) << e;
        if (cnt++ % 10 == 0) 
            cout << "\n";
    }
    
    
    sort(randomIntegers.begin(),randomIntegers.end());
    
    cout << "\n" << "\n" << "Sorted vector" << "\n";
    cnt = 1;
    for(auto e : randomIntegers)
    {
        cout << setw(4) << e << endl;
    }
    
}

[JLBorges]

int prev_val = randomIntegers.front() ;
for( int v : randomIntegers )
{
    if( v != prev_val ) std::cout << '\n' ;

    std::cout << v << ' ' ;
    prev_val = v ;
}
