Possible to read integers as integers?

Question:
Is it possible to read integers from a file as integers, or must I read them as strings and then convert them to integers?

Answer:
In C++ the streams libraries provide a type safe input/output mechinism. Here is an example of how it is done:

int i;
cin >> i; // this reads an integer from the standard input
All conversions from string to int are done by the stream.
