Hi,
I have a n X 2 matrix stored in a text file as it is. I try to read it in C++
nb_try=0;
fin>>c_tmp>>gamma_tmp;
while (!fin.eof( )) //if not at end of file, continue reading numbers
{
// store
cs_bit.push_back(c_tmp);
gammas_bit.push_back(gamma_tmp);
nb_try++;
// read
fin>>c_tmp;
assert(!fin.fail( )); // fail at the nb_try=n
if(fin.eof( ))break;
fin>>gamma_tmp; // get first number from the file (priming the input statement)
assert(!fin.fail( ));
}
The first assert failes, i.e. fin.fail( ) is true, when nb_try==n, which happens when it tries to read the first number which does not exist. But how come fin.eof( ) is not true after reading the last number? Does it mean it becomes true only when reading the first number that does ot exist? Also is it true that fin.fail( ) and fin.eof( ) are becoming true at the same time?
Thanks and regards!
