Loop to load incremental string names but with different prefix and suffix

I am trying to load at each loop increment a new image from a sequence into a variable with openCV for C++.

I am running into a problem because only part of the name changes in the middle but the prefix and suffix don't.

Here is the file name : 9987-1-0001-357.033.png

Next one would be : 9987-1-0002-357.066.png

As one can see, the number of the frame changes and the timestamp.

I am trying to find a way to automatically load the next image into a variable using C++.

Is there a way to abstract the timestamp to only increment a counter on the number of the frame (9987-1-000*.png ?

Thanks a lot in advance.
