You probably want to start it in a terminal then attach to it.
The program's output will go to wherever it was originally directed.
It's possible to change this (in Linux anyway) but that's a different topic.
You should understand what that means when running gdb.

https://sourceware.org/gdb/onlinedocs/gdb/Input_002fOutput.html
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/developer_guide/debugging-running-application
for more: google gdb attach to running process stdout example

In Eclipse there is a run/debug configuration called: C/C++ Attach to Application
It's similar the C/C++ Application but obviously doesn't have the Arguments and Environment tabs.
Here's the eclipse wiki on debugging: https://wiki.eclipse.org/CDT/User/FAQ#Debugging_C.2FC.2B.2B_Projects

Note: the program will run until you attach so unless your code takes this into account by waiting until you attach you can't debug from its start.
