help help to build array for numbers and sort

[programmerperson1]

#include <stdio.h>

int main()
{
 
  int y[] = 0;
  int p;

  srand((unsigned) time(&t));

  for (p = 0; p < 20; p++)
   {
 
      y[p] = rand() % 20 + 1;

   }

this will make me 20 numbers but and not sure about sorting

#include <cstdio>
#include <algorithm>

int main()
{
 
  int y[20];
  srand((unsigned) time(&t));

  for (p = 0; p < 20; p++)
   {
      y[p] = rand() % 20 + 1;
   }
  std::sort(y, y + 20);
}

thank you for help

looks good

things become so standard eh that maybe
we no longer know how to program a sort function?
