really easy c++: Does the operator >> in fstream remove newline characters after reading something?
c++, fstream
Solution
It leaves the delimiter in the input buffer, so the next character you read will be a new-line. Note, however, that most extractors will skip white space (which includes `new-line`) before anything they extract, so unless you do call something like `getline` this won't usually be visible.
Edit: to test on something like ideone, consider using a `stringstream`:
#include <sstream>
#include <iostream>
int main(){
std::istringstream f("12\n13");
int n;
char c;
f >> n;
f.get(c); // get takes a reference, not a pointer. Don't take the address.
std::cout << "'" << c << "'";
return 0;
}
I wouldn't expect to see a difference between a `stringstream` and an `fstream` in something like this.
Problem
``` // file.in 12 13 // main.cpp fstream f("file.in", ios::in); int n; char c; f >> n; f.get(&c); ``` After extracting the number 12, what is the next character? Is it newline or '1'? If I call getline instread of get, do I get an empty line or '13'?
