How to parse the file using C++

[Man4ish]

Hi ,
I am trying to parse one file sdf format having molecule information.
e.g
1 2
2 3
4 6
4 7
$$$$
9 2
4 3
6 6
4 7
$$$$
1 2
2 3
2 6
4 9
$$$$

There are three molecules each ending with $$$$. I am able parse the information for each molecule but how can i get different -different molecule ,is there any split and join function like Perl so that i can join the file with newline and split the file into different molecule using split function (tokenizer $$$$).If yes please help me out of this pblm.
Thankyou very much in advance.

I'm not sure I understand your problem.

However, assuming it's just reading the file and youi know the format, why cant' use use the >> operator to read the 8 integers and then use cin.ignore() to eat rhe $$$$. That would fetch out one set of data.

You then repeat for the other sets.
