How to join several processes in the shell?

Question

So, I made a small C ++ binary to connect to the command on the server to test it, so I started working with the following shell script:

#!/bin/bash

for ((  i = 0 ;  i <= 15;  i++  ))
do
   ./mycppbinary test 1 &
done

Now I also want to know how long all the processes take. I believe that I will need to make a time command for each of these processes?

Is it possible to join these processes as if they were a stream?
