Resuming a stopped process through the command line

I created the following C code on Linux CentOS to create a process.

#include <stdio.h>
#include <unistd.h>

    int main ()
    {
          int i = 0;

          while ( 1 )
          {
                printf ( "\nhello %d\n", i ++ );
                sleep ( 2 );
          }
    }

I compiled it into hello_count. When I do ./hello_count, the output is as follows:

hello 0
hello 1
hello 2
...

until I kill him. I stopped execution using the following command

kill -s SIGSTOP 2956

When i do

ps -e

process 2956 ./hello_countis still indicated.

Is there any command or method to resume (not restart) a process with process ID 2956?

In addition, when I stop the process, the command line displays:

[1]+ Stopped      ./hello_count

What does the [1]+line above mean ?
