size_t count=0;

std::string vowels ("aeiouAEIOU");

std::ifstream ifs;

ifs.open ("test.txt", std::ios::in);

if (ifs.bad())

{

ifs.close();

std::cerr << "Invalid input file.\n" << std::endl;

return;

}

while (!ifs.eof())

{

char c = ifs.get();

if ((c>='a' && c<='z') (c>='A' && c<='Z'))

if (vowels.find (c) != vowels.npos)

++count;

}

ifs.close();

std::cout << "The file has " << count << " non-vowels.\n" << std::endl;
