Just read the boolean variable:

bool b;
file >> b;

where file is your input file stream. 1 will be converted to true, from 0 to false.

If you've read the line, the obvious way to do the conversion is to look at the first character:

string s = .... // populate
bool b = s[0] != '0';

but I don't understand why you were reading the line if what you really want is a bool.

bool b = (variableFromFile != 0);
