How to read formatted data in C++?

Question

I have formatted data like the following:

Words          5
AnotherWord    4
SomeWord       6

It's in a text file and I'm using ifstream to read it, but how do I separate the number and the word? The word will only consist of alphabets and there will be certain spaces or tabs between the word and the number, not sure of how many.

Answer 1

Assuming there will not be any whitespace within the "word" (then it will not be actually 1 word), here is a sample of how to read upto end of the file:

std::ifstream file("file.txt");
std::string str;
int i;

while(file >> str >> i)
    std::cout << str << ' ' << i << std::endl;

Answer 2

The >> operator is overridden for std::string and uses whitespace as a separator

so

ifstream f("file.txt");

string str;
int i;
while ( !f.eof() )
{
  f >> str;
  f >> i;
  // do work
}
