Reading Custom File Structures in C++

Vote count:

0

I have a text file with this structure:

[NODES]
0 0
2 2
3 0

[Elements]
0 1
0 2
1 2

I would like to read this file into 2 arrays: Nodes and Elements. Can someone help me with the code for this in C++? I'm clueless about how to instruct the program so it knows in which matrix it should write the data.

Thanks.
