Thread: Get an int from a file

Does anyone here know how to get an int from a file?
What i mean is, take some numbers that are in a file, and store them in an int variable. when i try to go:

int buffer;
file.getline(buffer, 10);

it gives me some error about cannot convert type blah blah

and when i try to go:

char buffer[11];
file.getline((int)buffer, 10);

it gives me the same error =[
