Am i using ifstream::fail() method in bad way? - c++

Question

I have the txt file which contains for example:
Arthur 20
Mark 21
Josh 12
The are no empty lanes between, its only for readability!
What I want to do is write it on the screen in the same way as it is in the file.
I tried to make it this way:
ifstream file;
string word;
file.open("data.txt");
while(!file.eof()){
file >> word;
if(file.fail())
break;
cout << word << " ";
file >> word;
cout << word << endl;
}
But the output is:
Arthur 20
Mark 21
Josh 12
0
So why this 0 is being caught as a empty line to my string variable? I thought that fail() should stop the loop and leave me with correct output?

Answer 1

as long as you have names which don't contain white spaces and age as integer then you can read name as a string and age as an integer.
you don't need to check whether the file was successfully opened or not you can just abbreviate the operation:
#include <iostream>
#include <fstream>
#include <string>
int main()
{
std::ifstream file;
std::string word;
int age;
file.open("data.txt");
while( file >> word)
{
file >> age;
std::cout << word << " " << age << std::endl;
}
std::cout << std::endl;
return 0;
}
if you want to use one variable and for sure a string one then:
while( file >> word)
{
std::cout << word << " ";
file >> word;
std::cout << word << std::endl;
}
I don't see any good thing to read age as a string and maybe later convert it back to an integer!
the output:
Arthur 20
Mark 21
