#include <fstream>
#include <iostream>
int main(int argc, char * argv[], char * envp[]) {
int n;
std::ifstream filein;
filein.open("somefile.txt", std::ifstream::in);
if (!filein.good()) {
filein.close();
std::cerr << "ERROR: unable to open file \"somefile.txt\"" << std::endl;
return 1;
}
filein >> n;
if (filein.good()) {
std::cout << n << std::endl;
}
while (filein.good()) {
std::cout << n << std::endl;
filein >> n;
}
filein.close();
return 0;
}
somefile.txt contains a 1
but mingw-w64 outputs
1
1
this happens with 20111127. it happens with
I have tried rearranging this to
#include <fstream>
#include <iostream>
int main(int argc, char * argv[], char * envp[]) {
int n;
std::ifstream filein;
filein.open("somefile.txt", std::ifstream::in);
if (!filein.good()) {
filein.close();
std::cerr << "ERROR: unable to open file \"somefile.txt\"" << std::endl;
return 1;
}
if (filein.good()) {
filein >> n;
std::cout << n << std::endl;
}
while (filein.good()) {
filein >> n;
std::cout << n << std::endl;
}
filein.close();
return 0;
}
but it makes no difference. same result. this also happens with mingw also.
