Question

I have some input file that looks like this:

asdfasfasfas....

asdfasdfasd....
asdfasdf....

asdfsadf...

I want to be able to read line by line the whole line, without skipping the blank lines in between. How can I do this? Each line has no white space in it, but if I simply read in and process as:

 std::string line;
 file >> line;
 Foo(line);

Then it skips the second line and jumps straight to the second. I don’t want that to happen. How can I work around this?

Answer 1

You can use getline to read line by line, rather than operator>> that will skip the spaces.
